I race a 434 stroker in my dad's nova 1963 went 6.18 on the 1/8mile on alchool and non ported heads and intake :D Man what a blast!! the old 383 was pretty good though 6.36 on gas with ported heads very strong engine
with a 434 , i think i would shoot for the best torque reading over a broad scale , instead of peak hp ,, the long stroke may not peak as high as lets say a 406 , but the torque it would make would be awesume
i'd say 750 hp is very achieveable with the combo ,,, i had a friend buy a 18 degree set up from a truck team , it went on a 420 sb ,, it went 715 hp , using a circle track cam , mainly for bottom end ,,, a drag racing cam for topend ?? it should top 715 easy
yea, it runs on 110 octane. The whole motor came out of a craftsman series truck. we just bored it and stroked it to 434. The block and heads are all GM. The car ran a 10.44 @ 134 in 95 degree heat this summer and speed world in Arizona
Sounds nice ... I am ordering ohio crankshaft 434 shortblock motown block 4' 4340 crank 6'H-beam rods 13.5 1 JE pistons using my heads AFR 227 cam lift is 625 625 .... Looking for 700 plus Hp its gonna run alky fuel !!!
The car ran a 10.30 @ 136 mph on the second run ever. that kind of mph doesn't come from 500 hp. Did you think we guessed the Hp from the back yard stand run?
The 434 did make 740 HP under full load on an engine builder's dyno, (several passes ... the first pass was 690 HP stopped at 6000 rpm) And they did not build the engine, therefore "no dog in the hunt", they were just there to measure output and tune their carb. The key to this kind of output is 18 degree aluminum heads, and a very nice cam from "Bullitt" cams.
dont know about 742 hp....any motor will rev quick and high rpm fst with no load on it, as well as no converter hooked up or anything..lets hear it in the car, under a load...I am betting 550 hp--maybe 575 at the top...to smooth...whats the cam curve in this motor?..pistons, etc?...
what size heads and valves?
