Re: GUESS MY Horsepower

Your comments about your heads are pretty vague, are they fully ported heads?

I'll say 440rwhp with ported heads.

That clutch company is spelled McLeod.

Just curious, why would you go through all that effort only to keep the stock valve sizes? Nice flow numbers, but still...

Alot of head porters dont believe low cubed motors benefit from bigger valves. If anything it can hurt. From what I understand it can mess with velocity as well. LS1derfull can shed some light if he comes in here. Im no head expert
