Looking to stroke my LQ4 (4") that is already .030 over and machine shop says they need .0015 to clean it up so next step of off the shelf pistons are .035 but weisco is back ordered for over a month on the pistons I need. I have LS3 heads im using.

To meet my CR goals of 11.5-11.8 I need to get wiseco or diamonds

wiseco
.035 Back ordered for 4 to 6 weeks ($759)
.065 back ordered till 9-25

Diamond (got a great sale price of $739, retail of $949)
.030 Ready to ship now (bore will need to go .0315 to clean up)
.070 Ready to ship now

I have been searching all day and I see some guys go .125 over in rare cases on lq4 but im curious if .070 is really just stupid to go. I know no one can say but guess looking for response to anyone that has gone that far out.

I will have the block thickness checked and from what I see .300 (or .1?) seems to be what you need left to be able to run it? I plan on staying N/A with maybe a 150 shot in the future.

 

Get it sonic tested.. And go from there..but dont push ur luck man!

 

I just ordered wiseco .035 pistons about 2 months ago, and they were on back order, I figured it would be 3 weeks or so, but I ordered mine through Tick and had them in a week

 

The block ended up get hones to .031 to get it cleaned up and new diamond pistons -15 CC for turbo build.
