If I am looking for 750RWHP, do I really need bigger valves?
My soon to be brother in law is the port and polish guy at a local machine shop, so basically, I am getting it done for free, along with the lower intake runners extrude honed. I will run a custom intake manifold, and probably the 272/272 cams.
Will I really see much of a gain, and if so, how much of a gain using larger vavles. If your torque drops off over 7K, why would you need to accelerate past that, so who cares about horsepower. So what, at 8K I may push another 50-75hp, but it won't make me faster in the 1/4 mile.
I have searched, and people just said......Oh, you should do it anyway, but nobody ever posted any results.
