The heads had little work done to them,flowed .297@.600 or.650. Dynoed the motor using a SMALL set of headers and a worked over 850 carb(needed a 1050 dom) and it made 614hp@5400 and 688tq@4400.

A couple of racers I know use that exact combination.It works real well.You need to upgrade the valve springs to make it last.I use Comp 928's for that setup. Keith www.dunnuckracing.com

I put Eddie RPM's and a 590 on that shortblock, and the 2nd pass with no tuning was 10.69. The seventh pass I hit it with 250 out of the hole, and stacked 175 on it in 2nd... it kicked a rod at 1100 ft, and broke the cam in 3 places on it's way to a 9.21-141. That was the end of my experience with that combo!!! 6297527-FinishLineSpdwrld.jpg (205 downloads) "Livin' in a powder keg and givin' off sparks" 4 Street cars, 5 Race engines
