Budget 318 build

Ok thank you buddy. What kind of performance difference can be expected from a ported 318 vs a ported 360 with simular just a little lower Cr from a street aspect not turning one 5 grand plus I want 0-60 and cruising? Is it work the extra 150+ In machine work?

I'd say if your 0-60 and off idle is most important, and if your keeping 3.23's or less gearing with stock converter, then I would do the 318 heads with good valve job, new springs, and "MILDLY" open up the bowls. You'll be on the plus side of 5 grand rpm's.
If you want to build for the big end, then go 360 heads. I'm not going to read through the 7 pages to see what you have for gears, converter. IF your going 3.55's, aftermarket converter, and headers, I'd really consider the 360 heads.
