Thanks for responding. All right here is what I did. I just got the pistons and yes my dumb a.. got 427 car pistons. The machine shop called me to inform me. The stock crank is good and so are the rods. I am assuming they are heavy duty since they came out of a truck. Are you saying that I could use the stock rods and a 454 crank? or the stock crank and longer rods? Which would be better. If I can use the stock rod with a 454 crank that would probably be best because I will get more cubic inches....Is that what you are saying.

I am pretty new to this so I just want to make sure I have it correct.

Thanks
