Long Rod Piston Question

[2004LEBanshee]

I was told that my motor was bored to .40 over. But Im looking at the lable from the box of my piston it says.

 

795MO6500

Clear:0.0030

2559cd CW 16 S486

121306/3/D/9402

 

I dont know much about this. But doesn't 0.0030 mean .030 over not .0040? It has been 3 years and it runs great so im sure there is no problem. Just curious. ALso I have been looking around and I only see pistons for .20 .40 .60 .80.. No .30 What gives?

I believe the Clear:0.0030 is the piston to cylinder wall clearance.

the 06500 is 40 over (stock being 64.00, 10 over being 64.25, 20 over being 64.50, 30 over being 64.75 and 40 over being 65.00) the 0030 is the piston clearance (piston measuring 65.000 bore measuring 65.003)

 

either way, your 40 over.
