I gotta agree with George here... it will take some serious work around to make these work the way you want.

I don't think milling the heads to get to 60cc will cause you any problems, but they will become weaker for real extreme boost and power. Get yourself some wiseco -11's or something and call it a day. Can you sell the pistons for more than you are into them for?

I'm prolly just gonna buy a set of wiseco 4.030 -9cc or -11cc .945 pistons and call it a day... Run them with a set of genIV rods and arp bolts...

I'm pretty sure I wouldn't have a problem getting what I have in them back... I think they're at a real good price

I'm also gonna need a cam spec'd for this motor.... Uhh uuhhhmm, Vortec350ss! You seem to be pretty knowledgable in that area.

Do you not have the rotating assembly? If you were limiting yourself with stock rods, a stock piston is fine. I'm building a stock LY6 now with gapped rings. It should be plenty strong for what I want to do. What are your power goals?

Yes I do, but I have to bore it at least 0.010 over to clean up one of the cylinders.. I'm just wanting to see around 7-8 at the wheels. Does a company make stock Pistons .010, .020, or .030 over?

Open that sucker up .030 and put some forged wiseco pistons with forged scat rods and be done with it like i did on mine. My 370 with 70cc heads is at 9.8CR.

This is more than likely what I'm gonna end up doing... Might as well spend a few hundred more and put some nice rods in it too! I think I'm gonna do the 80e swap and keep the 5.3 in there for a little longer, until I get done with the ly6
