Hey guys, I'm gonna be doing a rebuild soon(forcefully). Well anyways, I was considering the stock usdm itr .25 overbore pistons machined to fit my ls rods. My questions are: What will my c/r be?? And, will I have any clearance problems??

thanks.

 

Come on guys. Sombody's gotta know???

 

the CR would be about 10.8:1 maybe even closer to 11:1

you will not have any clearence problems with those pistions.........the only problem i see you having is running nitrious on those garbage pistions. they really dont like that much stress and heat..........your better off buying a set of forged pistions........they will last much longer.........

 

I have it, its nice.
