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!

It's just a toy. It's a turbo 350 haven't bought a stall yet was gonna wait on it. I have 4.86's in it now but will probably be changing them. Had a Small Block in it before. It's a 84 Monte SS been gutted except for the drivers seat. I am running 29's on the rear now. Anyone have any suggestions on a 1/8 mile gear for a Big Block? . Thanks

I have a 366 out of a truck that has 40,000 on it, it burnt a hole in a piston can i use the crank and rods out of it in my 454 and make a 427? Thanks
