Attn: Pat McCarthy... i need advice
It seems your the man on this forum. So here i am asking you a couple questions.
I am building a bracket race 402, the heads are port/polished 820's with 2.19/1.88 and have been cc'd at 113. I have a comp cams 292dur. 550 lift hydraulic cam. Victor O intake and a quick fuel 750 holley.I have scat rods w bushed ends and cap screws. The crank was check and is straight and polished.
Its going in a 70 chevelle with a t350, ati converter, 4.88, and a 30"x9" tire. It weighs about 3650 w/ driver.
I am in need of a set of forged pistons and im looking for around 9.5 -10.5 compression. I was thinking something TRW. What would you recommend without buying custom.
What kind of hp and torque should an engine like this make?
How fast do you think it will go?
This is my 1st bbc venture. The reason for the 402, the price was right for a carb to pan low miles engine.
Thanks,
John
