Just a few ideas. I'd start with a re-cuvre kit for your distributor, if that doesn't get all you want, open up your exhaust maifolds by using a die grinder, or better still find a set from a 340 or 360.You could take it up a notch by having the heads decked 20 thousadnths or so,just remember to have the intake done too,or it will leak like a seive.Gasket port matching and a bowl cleanup port job also would help to wake the little motor up,and the best part is, other than the decking you can do most of this stuff on a week-end afternoon for little more han the cost of gaskets. Haven't seen anyone mention a Hughes cam yet,but if you know how your engine makes compression,they can go a long way toward really helpimg an otherwise stock engine.Just a few thoughts before you yank that 318. My first 318 was in a 74 Chaallenger,I used some of these tircks,and when I'd beat a bigger motor at the strip, the look I always got when they heard, no "it's just a 318" not a 340 or 360, was Priceless. Best of Luck and have fun with your build.
