Best 273 and 318 builds (NO 360's please)

Wow thanks for all the input. My little 318 is just waiting to be redone.
Anyone know what the cheapest reliable 350 horse combo would be.

I plan on doing it myself. No expirence so I do not want to get to fancy on this one.

Try a 9.5-1 max compresion engine with 360 heads (Or bowl ported 318 heads. Your looking for about 220 cfm intake flow and approx. 70% of that for the exhaust flow.) and a Comp Cams XE268H or 340 cam, headers with a free flowing exhaust @ 2-1/2 inchs and a H pipe. RPM intake and a 750 carb.

This should be worth 350 HP (5500) and about 380 lbs of torque. (4000)
