I am trying to put together a backup motor and I have a set of pistons for a chevy 400 on 6.0 rods I bought at an auction. The pistons have a part# cast in them 1368p in my books this seems to be a ohio cast piston # or One Performance Engine Parts I think they are now called. All the books I have looked at have a 1369p # but dont show the 1368# I need to Know the approx comp ratio this piston has with a 64cc head. It is a flat top piston with a trench releif.
Thank you

What did you pay for the pistons if you don't mind saying. I got a buddy that has a set of forged ones he wants to sell me.
