Scream'n 318 ?

Hysteric said

I had them on a low comp 360 with a 1.84 valve with very little if any porting. All I can say is that the acceleration was nothing short of astounding, brutal but beautiful all at the same time.

It had a 256 @ 0.050 solid but still made 185 psi on the comp test.

The real reason they're attractive to me is that I already have them, and it will be a budget build. That, coupled with the closed chamber. Valves are tiny, but that can and will be addressed.

Seems most people go the other way - 318s with 360 heads. Interesting that you did the opposite.
