Suggestions for a 318 build

Interesting combo there joe.

Fish, I'll stick with a 3.55 rear axle combo thoght pattern and leav the 4.10's for some other day. Stick with a tire no larger than 245/60/14 (25.6 inchs, 26 inch acceptable)

A Comp Cam XE274 (1800 - 6000 rpm) and a 2200 stall converter inside a 9 - 9,5-1 ratio engine should do ya very well. Your biggest problem is air flow, AKA head flow.
This is the toss up between 360 heads and ported 318 heads w/360 valves.
Use a dual plane intake and a 600 - 650 cfm carb. (Weiand Action plus or a RPM are very good for this set up. A on the cheap would be ethier a Edel. Performer or OE Iron intake. They'll still work well.)
TTI makes the best headers, though expensive, there worth the price.
2-1/2 max size exhaust pipe. (Into a X would be great.)
