The pistons have 423Np stamped on them. Probably a rebuilder piston. Like i said i jumped the gun on this deal and bought the thing before i did research on the pistons.
Looks like I would be lucky to have 8:1 compression with these pistons and probably wouldnt even have that.
I dont want to build a dog of an engine i want good quench and strong compression. I have been looking at H345CP speed pro hyper pistons, they state 9:25 compression with a 64cc head.
Now I am wondering about my rods, I know they have been "resized". Does that mean I should NOT be looking for a piston designed for a 5.7 rod?
I cant seem to find a weight spec on either one of these pistons and I know about balancing issues....
