i have a 454 bbc for my show truck. i am getting some money back from the tax man this year. and i would like to spend it on the bb and get a full reto fit roller cam kit for it. and i already have full roller rockers for this truck. this is all going in the truck in my profile. i was looking at a comp cams 4x4 cam. do you think it will be worth it for the money or not?
