BIG BLOCK BATTLE! TRANS AM 455 OLDS Vs TRANS AM 474 PONTIAC

[dcmartin11]

The correct term on Pontiac v8s is intermediate block sence pontiacs are to big to be small blocks and to small to be big blocks, a 326 is the same block has a 455 cept it's journal and bore are smaller meaning if you consider a 455 a big block then a 326 is a big block, if you consider a 326 a smallblock then a 455 is to. Calling any Pontiac v8 from 59-79 ( cept the 301) a smallblock or bigblock shows lack of knowledge about Pontiac history.

[traxxasrccars]

I consider the 421,428,455 Pontiac big blocks. I do like all Pontiacs and had my share of 350's 400's and 455's and my best one was the 71 455 with a ram air cam. The nice thing is they share a lot of the same parts. There is many differences on the motors depending on the year they were built. 1976 was the last year they built the Pontiac 455. That's why they started using the olds 403,and chevy 350.

[deannaber]

There all big blocks i would think the 326's and 350's are actually heavier because of the smaller bore

[traxxasrccars]

Pontiac 400 has a 3 inch main and 455 has a 3.25 main

[undercoverLsX]

@traxxasrccars

Not sure if you're trying to justify pontiac has a big block or not, but the main size has nothing to do with a big or small block, you can essentially have any mains you want in any block. Chevrolet Small Blocks had 3 different main sizes, and at least 6 different bore spacings.... from 262-400

[bubbasoneddy1]

there are only 2 gm engines. both 455. one olds, one pontiac. nuff said.

[BklynRulz]

@bubbasoneddy1 Can't forget Buick's 455.

[somemadlebs]

call it BIG OLDS POWER

[84cutlass403]

heyheyhey id rather not fight with other gm guys and rather wipe the rice off the streets (ie four cylinder cars with just exhaust that claim to be fast

[peak199]

some call pontiac motors big blocks because they are''tall deck'' motors.

[JimJamBoneMan]

who i their right mind would destroy a pontiac, especially a trans am, with and Olds engine? shameful

[Seandude23]

@JimJamBoneMan the 77 Bandit and many other trans ams were actually factory built with oldmobile engines..

[ilshwak]

@JimJamBoneMan

Olds engines are boss.

[bad67pontiac]

For yor information no one recongnizes that little 301, but as a technicaltity you are correct. As for as your response about the pontiac 400 making Pontiac. I would have to say that your slightly wrong.

What made Pontiac come to the for front (or as you say it ) made Pontiac would have to be putting that first 389 in a mid-sized car. Secondly then with perfect timing and fantastic advertising By Jim Wangers puttting Pontiac on everything from magazines, to movies, to the tracks. U R wrong.

[hatinnd]

lol I had a jackass reply to one of my videos too! Good to see I'm not alone! don't let it get ya, you're not alone either!

[MySickstring]

Are the cars battling or is it the commenters below?!? Get over it, Gentlemen. Nice video anyway!

[gypman921]

but even upon seeing my folly i see you still love to rant. Which im thoroughly enjoying. what are u in youre 20s still..lol..but nonetheless i may have been wrong but as i said every shop i been to referred it to the big block pontiac so what but hey you love to carry on so go jump in youre 91 sunbird with youre fart can and enjoy.You need to grow up bro.i can except i was wrong but you cant obviously.but its cool i enjoy youre rants for they are funnie as shit thanks for laugh if nothing else

[gypman921]

maybe they referred to is as big block due to large displacement or larger journals or what have ya but who cares its still known by alot of of people as a big block regardless of casting size so take youre im right card and carry the hell on.

[bad67pontiac]

This is for gyp(wuss),you my friend are incredible. You finally admitted that you dont know shit about your 3" wider heads on your Pontiac (lolololol), that was the funniest comment I have ever heard. Then my sad little friend, (and I do mean sad) . You have the nerve, the fortitude, the audacity, as well as the daring, fortitude, or the rancor to even respond like that.

You my little friend are just that, little in so many ways, please do yourself a favor and dismiss yourself from here

[gypman921]

lmao wow dude you are the who i amazing with youre words sounds like a dying whale. i admitted nothing i said i was going to research it. i merely steered you to learn to read a previous comment. I ve had a 67 GTO for 8 years with the 455 and i merely said it appears significantly bogger than the 400 or 389.. Each time i got parts for it pontiac performance referred it to the big block. And yes its a roller motor i imagine next youre gonna say the 455 never came in a 67..

[gypman921]

LMFAO...lol dude youre 55 and you rant like a adolecent. WOW u r genius sheer genius. i cant wait til you come at me with a new insult. Gyp wuss thata a good one i supose doo doo head is next from youre book of immaturity. My 9 year old son should take a lesson or 2 from ya. LMAO. GROW UP OLD MAN i can take that i mistaken but you need to take a geritol and get over it. gyp wuss lol thats awesome by a sesame street standard

[bad67pontiac]

Hello again gypo,gypster, gypwuss. Thanks for your kind words and compliments, and oh yes your reply. I am sure that you had to look up some of the words that I used earlier and it made it difficult for you no doubt.

Anyways your intent of your reply was good enough for me. Its a step up from any of your previous ones, must have had your 9 year old compose and write it for you. I have to admit its better than what the ole man can do.

There is more on this issue that you have missed, Icanhelp

[gypman921]

lmao.. wow i see that you old man is fighting hard to hold on to adolecence. i futile fight however admirable. Please keep with the insult altho i may have been wrong theyre grampsi see that you still love to insult. and the names that you say arent even really insulting but humorous. Grow up take a geritol wash it down with a ensure and enjoy. im enjoying watching you make a ass of yourself with petty words as well as the other people here.. thanks for laugh im enjoying it. GROW UP!

[bad67pontiac]

Everyone has someyhing either faster of slower, thats not the point here. What is the point is the fact that people like gyp(woman) thinks that they know everything there is because he (they) run 12 seconds in the quater mile. Congrats on the effort, .......... but you suffer from the same problem the LOSERS on American Idol do ..........(you know the ones) that say they are all that then cant sing worth shyt. Thats you gypman from top to bottom, front and back. No need to reply your garbage.

[SuperWadester]

go Pontiac!!!!!!!!!!!!

[lronBar]

the point is, and its true, that all of Pontiac's V8 blocks were the same. The only one that was different was the POS 301. I was surprised to learn this but I did when I bought an 80 Turbo with a built 455. Even the 301 had the same motor mounts as all the rest.

Pontiac always had the best engineering of all the division, I don't care what you try to tell me.

[lronBar]

*Not the division, the whole corporation.

[vistacruiser67]

Oldsmobile was the best engineered.

[vistacruiser67]

Pontiac's strength was their styling.

[net0dotcom]

Pontiac only made Big Blocks unfortunately. Even their 326 and 350s are heavy big blocks. They did not make a small block.

[bad67pontiac]

gypman is an idiot, NO Pontiac themselves never produced a BIG BLOCK. The blocks where all the same to save on production cost. Now if after market companies modified or changed what the factory did thats different. But Pontiac themselves never made a ( BIG BLOCK) for the public.

[gypman921]

you my friend is a cook i have a 67 gto with a 455 roller in it and unless my eyes mistake me the block appears wider but hey i been known to make mistakes so fuck off ass hole. it appears wider than the 400 and 389. jesus christ and besides i am doing my research and finding out for certain so go fuck yourself eh

[bad67pontiac]

gyp(woman)......... you must have your head squarley up your azz, read what you type, then go do some homework. I see you know how to cuss with the best but that means nothing, now if you ONLY knew how to read a book anout your so called (WIDE) Pontiac block................lolololol­olol...........you are a joke go buy a Prius its more your understanding.

[gypman921]

lmao you are my hero truly. bravo and no i dont know everything but apparently you do eh? lol i admitted i could be wrong but am reseaqrching it learn to read bub i can own up to my mistakes. I simply said my 455 appears wider than the 400 and 389. holy shit ill do research go do hooked on phonics jack ass

[Gaspipenicklioni]

@bad67pontiac Pontiac did produce big blocks. The 326 all the way up to a 455 except with the 301 being a "metric engine" as it was a smaller block of it's own. FYI, the 400 is what made Pontiac.

[gypman921]

@bad67pontiac Not to rain in on youre parade but it was the journal size that classified them as small blocks and big blocks. Sure it may not be technicall correct but hey it is what it is

[bluyack]

@gypman921 we are still on this issue..........geeze the mustang dudes even know the truth about the pontiacs.

[gypman921]

@bluyack hey just passin on the Info from a pontiac club in michigan. thats all...lol

[bluyack]

@gypman921 sounds like a few chevy converts.... that journal size thing is not the way to classify if there is such a thing as big/small block yac. if you say anything about big/small block to any vet yac, you will have you car guy card taken.

[bluyack]

how bout we do this the right way and just have a few blocks and heads, grind off all casting numbers and then we can figure out what is the truth, you will not be able to tell the difference unlike your chevy fans that you could actually tell the difference.

[bluyack]

@gypman921

[Ajacques8000]

Pontiac had no big or small blocks. they are all the same from the 326-455. different heads and stroke made the cubes different but ALL the blocks are the same.

[gypman921]

lmao are you serious dude i have a 67 gto with a 455 and i know for a fact the heads from a 389 are about 3 inches to short to bolt on...lol yes pontiac had big and small blocks. example fit a 301 pontiac head on a 400 block...........AINT HAPPENING. do some research before you type.

[bluyack]

@gypman921 you need to do more homework the reason you bolts dont work is because you put them in the wrong hole. All blocks are the same from Pontiac 326-455 from 64-81. why you would put 389 head on a 455 is dumb anyway. the only difference between the motors are the bore and stroke!! grab a book read up and if you want break out a ruler

[StSt89]

You would put 389 head on a 455 for increased compression. All head from 350 to 455 will fit on each other.

[bluyack]

@StSt89 true almost all the heads are interchangeable, but 389 head has a different valve angle,so if they are installed on a 455 you could run into clearance issues with the pistons.

[monabang]

@Ajacques8000

Yes they did. The 421.

[Ajacques8000]

@monabang no they didnt. do some research. all of the pontiac v8s are the exact same block. They are not considered big or small blocks. And even the pontiac 350 is the same as the rest. learn something before you get into an argument with a pontiac expert.

[xirxious]

@Ajacques8000 They did make the 301 in the late 70's which is sometimes called a smallblock, but no one who can claim to be a hot rodder wants one of them things.

Typically in the late 70's Trans-Ams, if you got a stick, you got a Pontiac motor. Automatics had 403 Olds motors.

[5gen67to10camaro]

@Ajacques8000 the 301 also used the same block the only difference was the heads and intake manifold

[ryanpushesthebutton]

@Ajacques8000 Thank you. no one sems to get that. Don"t get me wrong, i love my 455 but i don"t have a poncho 'big block'.

[Ajacques8000]

@ryanpushesthebutton ur a retard. i said that there is no big block. whats not to get

[MrAcidburn3110]

@Ajacques8000 I agreed with you bud. I have a pontiac 455 in my T/A. I don't have a pontiac 'big block'. 455 is the largest factory displacement poncho engine. However, the Pontiac 455 is NOT a big block. Hence, Pontiac doesn't have a big block... just (as you said I believe) different bores and strokes and in some cases such as the panzi 301 even a different crank journal size. Maybe. I could be wrong. I'm no expert simply an avid Pontiac fan.

[longrib2]

this is nice, you should see my friend restomod69; blakes 69 firebird- street/strip running 10.40's you can see mines at longrib2. keep the pontiacs rockin guys

[feedingfrancis]

whoever made this vid is a tard... a big block pontiac huh? there is no such thing... must be a chevy guy.... just like there is a ford big block? nope...

[xdawk]

what is the 385 series then?

[seventyeightwater]

ford 460

[68LPC]

400 pontiac 455 H.O. pontiac 455 SD pontiac 455 Ram Air pontiac

427 ford 427 cobra jet 428 for 429 ford 460 ford.

oh and by the way. pontiac was MADE to be a beefed up version chevy cars, so if anyone was making big engines it would have been pontiac, and they did.

[deohgesdad]

didnt know that..

[novajtv]

your video made me throwup in my pants...

[GoombaDaddy]

throwup in your pants lol! so you had your pants on your head then?

[deohgesdad]

teacher says if company makes large bore and small bore, the larger one is referred to as a big block.. it really means nothing. a few companies only had one engine, and there is no big or small block.. makes seance

[jeffdb3]

The block size refers to the size of the "block" of cast metal wich is then bored.

Your teacher is right that generally GM made one large block, bored to different piston volumes (400 -500) and one small block bored to different volumes (300-360). For instance, you cant tell an olds 350 from a 307 just by looking at he exterior.

[jeffdb3]

Also small volumes, with smaller bores, are inherently more resilient to stress, so manufacturers would sometimes skimp on the quality of the alloys in these blocks ...something to think about when you want to turn your 300 whatever into a 350 by reboring it.

[xxGriffonxx]

Pontiac 326-455 all same exact block with different bore

[boosborne]

pontiacs do not have big blocks. 400 cid and lower are considerd small journald motars and stuff like 421,428,and 455s are big journalmotors

[redneck2010]

they are considered different depending on what states you are in

[steelfury455]

you are correct sir. all pontiac V8 motors (except the 301) are "physically" the same size from the outside unlike chevy and fords. the cylinder heads interchange between motors which is very nice...

[76TransAm400]

very true. very true

[landytucker1234]

even since i was a small boy dat beautifull gargle has made m skin tingle.

N I STILL LOVE IT!

BIG BLOCKS KICK ASS!

[somemadlebs]

THE OLDS IS IN THE FAR LANE

[89shelbyvan]

Either way both big blocks are mean and fast. I love them Olds motors though. Tough as hell stock!

[86cookiemonster]

somewhere some camaro just shit itself.

[TransAmDrifter]

maybe the author wanted to tell us that one of the pontiacs was the older model :D (i guess the left one is '73 and the right is '78)

[TheBandit77TransAm]

which ones the olds and which ones the pontiac??? EVEN THOUGH THEY'RE BOTH PONTIAC TRANS AMS!!!

[somemadlebs]

THE OLDS IS IN THE FAR LANE
