rate this stuff for add some horses on a 318

I ran a 318 in a 73 duster years ago. performer intake w/ 600 holley. 1 5/8 headers. 10.5 rated compression but with 360 heads was 9.5. I ran a crane 302-312 504-528 lift cam. It was definitely overcammed but ran really well. I would definitely put stock valved 360 heads on with a gasket match and pocket cleanup. You will not believe the difference. Also tried a 3310 holley. 750 Vacuum secondary and that really woke it up also. I had a stock convertor 727 with 276 gears and was tearing up high 13 sec. cars with this. I don't know the weight but I took everything out. On paper this little car should have never have run this hard, but it sure did. Bottom line, 360 heads and a 3310 holley is what I would change. I also agree you need more gear, that is what I was really missing. I have BB duster now and run 355s and love them. Good luck and I cant wait to hear the progress, I have a soft spot for 318's after that one.
