KEVIN_TECHEE Posted September 15, 2012 Report Share Posted September 15, 2012 This is a long shot but looking for some one else that has a set of .31 over Wisco pistons that has one that has met its death to a valve. was thinking of building a short block this winter for some thing to do my other three are fine just need to pull the old block apart and start with a different block.

Marker1989 Posted September 15, 2012 Report Share Posted September 15, 2012 (edited) Were they shelf pistons or custom when you ordered them last time? Honestly, it depends on how old they are but I probably wouldn't re-use any of them, there's just too much room for variation if you were to throw one new one in with a set of used and abused ones.

Dad Posted September 15, 2012 Report Share Posted September 15, 2012 031??? or 92mm = .035? If they are the K555m92 then wiseco stocks them @ .035 oS. Dad Quote Link to comment Share on other sites More sharing options...
mstieg Posted September 15, 2012 Report Share Posted September 15, 2012 Dad is right. Yours is one of the 2 pistons Wiseco makes for their sales which they list at .031. The others .020, .030, and .040 over etc. are custom made for Dad @ 8:1 compression while ours are 7.5:1. Wiseco will sell you one probably. I just got rings for this piston that are sold for individual pistons. Quote Link to comment Share on other sites More sharing options...
