What combo? Wish I could do that. Actually, I now have an 81 Spirit that was going to get a 401, but I think instead a hot 258 would be neat. I have an AMC 20 awapped in with 3.54 gears, and a 727 trans. What would anyone recommendd for a cam? I think I found an Offy intake, I have a 600 Holley, ane will Jeep headers work or does someone make a set for the cars? Sure it won't be fast, but it'll be unique and fun, and a lethal bracket car ;\) ...
