Sorry if I am annoying anyone with all the post. I am making a list for this 351w I just got. Oh, by the way, we took the block to have it bored and cleaned to start building. We did all the work of breaking this thing apart the other night and didn't even notice the crack in one of the cylinder walls. Soo, I have to get a different block or sleeve this one. Anyways, what company should I order my pistons and rods from? I want to be able to handle 400 to 500 hp with no problems. What company can I order the pistons and rods already together? D.S.S., Probe Industries, etc..
