Don't let anyone discourage you. The Pontiac is a great, solid platform. Keep the 3.75" stroke motors with stock rods in the 5500-5800 rpm area and they will deliver exceptional performance. Keep up the good work!!!!
After running an engine dyno for years, there isn't anything about Pontiacs that I don't know. I know, for example that low RPM GMC truck engine (Pontiac, look it up) is good for boats. The chain slides nicely through the gap between the intake and the valley making it perfect for an anchor. That I DO know. Try buzzin' that 3'' main bearing slug 8500 like a Chevrolet and you'll shovel that bottom end into the scrap barrel.
@CrudeDude hey buddy, My firebird will smoke any chevy at half throttle...yea your little 350 chevy will put out 375-400hp but only at 350 ft lbs of torque....now a 400 will match that hp probably go above it AND THEN have close to 500 ft lbs of torque. so how about you learn something about pontiacs before bad mouthing them.
that trans am is sooo not junk, i have one just like it except sumone rammed my left fender and bumper, that ones in better shape than mine and i love it, buildin a motor for it now for $1400. cant wait.
hey im working on a 79 firebird and as of now it has a 301- but i hav in habd the 305 eng- with a 350 turbo tranny- how can i get about 400 hp outta this 305? thinking on a turbo- would it be woirth it?
dont bother that motor is no good no matter what you do to it you can get a junkyard 400 and put a stroker kit in it and get 400 plus for less than $2500 and that is less than a turbo and the 305 still wont be there .
hey hows ur holley treating you...i think i might switch to edelbrock...there to hard to adjust and the run like crap at idle..but do they ever go when there wide open ahhah
Its basically a stock 400 i put a 296 lunati cam in it and a decent set of 4x heads edelbrock performer intake and an 850 demon carb. Right now im installing a turbo it should be done soon ill post some vids.
Ahh yes, SBC open headers...I love it! Car looks sweet (although you may paint it). I'm not a superficial person when it comes to cars, id rather spend 2k on performance mods then a paintjob.
running an engine without an air filter for a short period of time is of no real detriment to the engine. As long as you dont suck in any leaves etc.....
im about to put the 400 in my firebird, its been long overdue! sounds great i think mate, all those who say its sounds like junk must be on something.
Thanks man its about time somebody appreciates the sound of a good engine good luck with your project man ill be posting some turbo videos soon check them out.
wow you have alot of haters here...anyways you have a pretty rough idle, doesnt sound too healthy. maybe your mixture is too lean, or maybe something else. anyways good luck with your firebird.
hey letmehang?? why is eveyone of you comments, something to do with gay, balls, fag,or in the mouthshit?? that talk you love to speak is called homosexual tendencies, you are really into porn& beating off i seen your kind chi-mo....
ya see, thats what im talkin about, another man asking another to suck his balls, youre straight gay dude dont write me again go find a woman who aint in the county jail...
Then fix the leak and the plug and post a new vid. If it leaks its a POS. Don't matter if its a Ferrari. Leakers are POS. A V7 sounds better than a V8? Whatever dude.....
i had that happen on my gto i just sprayed both heads with that high heat ceramic silver header coating then a light clearcoat of engine enamel everywhere except in that hot region.. nice carb by the way
if you put headers it should reduce the temp by a couple of hundred degrees the manifold restrictive design creates that super hot iron but who cares as long as it runs good
That's awesome. I just rebuilt a 1970 400 4-bolt main, bored .40 over, slightly higher cam, and put on an edelbrock manifold & carb - we just got it started yesterday. I dropped it in my 76 GP. Now, it's time for putting all the small things together (wires, brakes, etc).
Anyway, badass firebird. It's going to be REAL sweet when you're done working on the turbo. I like the color scheme of the engine. I don't see many Pontiacs painted green - it's cool, new look.
The bottom end is completely stock i pulled the 400 out of a grand prix checked the bearings they were ok so i slapped a set of 4x heads on it and a 296 lunati cam. Its basically just a test engine for the turbo if its works out ok ill build a stout 400 probably a stroker.
very sick engine man, gotta love those strong pontiac engines, im might be getting a 70, or 71 grand prix, you might see me post a video on it lol, what do you got in that beast?
Dude, I know a guy that has made a 71 GP go 5.5 0-60 and prob high 13's with just a stock pontiac cam swap. hit me up, he loves to help. my 71 Formula is about .3 faster now in the quarter thanks to him. and will at least that much faster when I get the parts.
Don't let anyone discourage you. The Pontiac is a great, solid platform. Keep the 3.75" stroke motors with stock rods in the 5500-5800 rpm area and they will deliver exceptional performance. Keep up the good work!!!!
