The Stock Crank is Cast, good for up to about 600 h.p.-Rods are o.k.-I understand it's good to at least .060-Yes, generally you can re-use the Lifters, but they are limited to about .550 in Lift, and, if they don't have flat spots or bad Rollers, should be fine-they are expensive to replace, so, if you are on a budget, just watch your Cam choice.

As for a Cam, you will need to give us a better understanding of what you want to do with the Car (your expectations), the weight of the Car, Transmission, Converter (if Auto), Rear Gear ratio, Tire Diameter and so on-the more info the better.

P.S.-if your Crank turns out to be bad, or you want to go over 600 h.p., let me know-I have a forged Crank (502-it will fit) that I would let you have pretty reasonably-good luck!
