bansman76 Posted June 8, 2011 Author Report Posted June 8, 2011 does it start with 513? if that's the case then they should be wiseco pro-lites. yeah they say 513 p 2 .. i thought they was wiseco.. but really wanting to know the size or what bore its on.. the guy i got it from said it was on stock bore which i now know is wrong..

camatv Posted June 8, 2011 Report Posted June 8, 2011 wiseco's when they were actually made in USA had just the part number and a domestic sizing. .20 .30 .40 over and were only labeled on the box as to what MM it is. 513 p2 would be a 64.50mm i believe. the newer ones that are overseas made junk are mostly the ones with the full part number and sizing on them, they droped the domestic numbers.. that piston today would be like a 513M06450 Quote
