Warehouses dont generally deal with the public,so...I think I'll go down to the jobber store and look through thier piston catalogues.Prolly find nuthin,but what the heck..
So far the best I've found is the speedpro with a 1.755 ch,a TRW with 1.759 ch and a sealed power with 1.759.And of course the KB at 1.81.
