Pontiac GTO 400 Engine 1967 Dyno Session Motor Test

[84firebird305]

I just bought myself a 81 trans am with a 78' nose to make it look like a smokey and the bandit TA. The car originally was a 4.9 turbo TA and they swapped in a 400 block , rebuilt the motor and put some goodies on it like a edelbrock air gap intake, holley double pumper carb, accel high voltage distributor, taylor wires ect. they also built up the tranny and put a uri ratchet shifter in. Turns out, after reading the codes off the motor, its a 400 block from a 67' firebird!

[musiclovr2]

need shorty hedders, edelbrock intake,and 750 carb, and youll see real results

you didnt say if it had ram air heads or not, or what cam, stock isnt just stock with those old ponchos lol, they do kick ass, now you can get a balanced stroker kit, ported heads,and pushem to 7k easy

I just had a Pontiac 400 given too me. It was found in a pile of scrap metal. Started taking it apart today and it seems to be in good shape. Its got some sludge in it, which has kept it from rusting. I plan to rebuild it and find me a 67 GTO

[MrBlinddog48]

what a waste of brains. u just wasted my time

[689321546]

all the pontiac crankshafts were only good to o......to 4,800 and then they would break i broke enough of them i know .

[kennethrobinson11231]

@689321546 You are full of shit, Come to my place and I'll show you a 428 @7200. You don't know shit about a Pontiac

[joseph19699]

what were the horse power #"s---- am guessing about 290 hp---my bud built a 69 400 stock everything, the camshaft was a summit grind 802--it made 380 hp on the dyno at PPR....and there was room for more...thanks for posting guys...

[gtolover1000]

@joseph19699 a 67 400 4 barrel made 360 hp in the books but they really made like 400 -410 hp

[jellis649999]

to bluesmagician....you should shut your yap and listen,you might learn something in your life for once

[trunk516]

7 and a half minutes and ya can't give the numbers?? Waste of my time..

[homecubed]

i just got done with mine all i have to do is paint the heads and put a air cleaner on it and it'll be ready for my 73 ventura

[demorgus]

torque is always more important to a street car,kickin ass with maximum fuel economy

[toothmaker22000]

turn the fuckin music down .i  wanna hear ya!

[hppyadam]

i like that dyno you cant kill old school.

[Ajacques8000]

what do u mean how did they get 500 ft/lbs? its a pontiac thats how. Sorry chevy motors just dont do that

[theclubman]

how did you guys get 500 TQ ? with 400 hp ?

[DuNZCruiser]

@theclubman .

Pontiacs are famous for that...

[pranksterright]

whats that song in the background?

nice engine, i love the 400's, real good engine

[SSBarracuda]

it is a Stevie Wonder song. Just love that Motown sound!!!

[crowerpower57]

I have a '86 GMC 2500 Pick-Up, Gonna put a 455 Poncho in it. Gonna build it for as much low-midrange torque as i can get for towing

[mitchelltom32]

my thoughts exactly cant beat the torque of a pontiac they run good in a truck they are nearly indestructable built right

[fireamracing]

it didnt take alot to make a 400 run circles around a chevy and at a low rpm not wide open like a chevy has to be when u run one.

[PontiacAlfaHSV]

True that, High Torque at low RPM. Smart power. Not Chebbie's High HP at HIGHER RPM.

[Fast355]

Secondaries are opening way too early on that Q-Jet. Tighten up that spring and it will counter the quadrabog tendency.

[bluesmagician]

why so much talking? Just run the motherfucker!

[SSBarracuda]

man, you are such a cusser!

[Camaro2007]

Its his video, So shut the fuck up.

[fireamracing]
