CudaFun - So not sure what the end results is wanted, but the little 440 you have has large potential in my opinion without having to go to great $$$ expense. If your looking for HP, I would keep it simple, 440 Source heads, send them to IQ52, little roller cam, steel head gaskets, headers, performer, convertor and gears. Oh and if you want to wamp those 505's/512's, this little 440 will handle 225 of nitrous without issue. (Have you seen how thick those cast pistons are??) MSD locked out with a digital box?
