Thanks Jmark, but if you had read, it already has motor plates to make everything else fit right. Woodsman, that is a beautiful car. The HP#'s are way crazy for me, what Series PC are you running? I went the cheap way out, I have a 463 built to the teeth. Was told it should handle 1600HP, no sweat. Then add my F-2 and intercooler. I was told by Jeff at RPD that it should be able to make 1000-1100HP on the 18PSI and 1500-1600HP on the 28 PSI pullies. I got a dumb question for you, I seen you said you had a Prostar 500 magnafuel pump too. Magna fuel says it will handle 1600Hp no problems but Jeff says it's not big enough to keep up. IS yours working out good? Jeff says it will lean out on a hard run, maybe that is your problem on the lean condition? I will go with the Mororso's. Right now I believeI have a lower 73 and upper 56 pulley. The pulley is 5 1/2"s around. What is the 54's size. As I think I need at least a 1/2" space for hood clearance. Thanks Breck
