318 1/8 time improvement

OK you Win !!!
Its not about winning but seeing how different people get things done and learning from it. The real questing is why can it go mid 12's with a small cam, stock gearing and a 2.5K converter with 225 street tyres.

Ported 318 heads will go into the 250+ range with good porting.
I agree as I have a set flowing 240+ cfm but with an 1.9 11/32 valve and a port volume somewhere in the 140's. I don't think you're gonna get 230's with a mild port job and a stock 1.78 valve. I have seen a set of super stock heads go 224 cfm but they're a work of art.
