rate this stuff for add some horses on a 318

With the size of the cam and the compression you have, a swap to mildly ported 360 heads would really wake it up in the top end and lower the compression a good bit to where you want it (mid-high 10's). The longer duration of the cam is helping it not to ping as much as it would with a smaller one. Then add some 3.91 gears and it will zip down the 1/4 mile in no time... might need some slicks at that point too lol In fact in my opinion you have a nice short block to make a real budget screamer of a 318 with those 360 heads and a small single-plane intake if you can find one.
