hay thanks crackedback for your info I have been out for a few days working night and day just got to read thats good a 11 will work do you see any thing I should change??????..
I had a 360 with 11.75 compression, ported J's and a .510 Comp cam and it built so much crankcase pressure it pushed oil out the breathers. 1 and 7/8 headers solved the oil problem, but it never did run right (not enough cam).
you're on the right track, this bunch will help you go like stink.
