A friend of mines dad works for a machine shop and he can get me a 350 4 bolt main block thats been completely machined for 100 bucks. But my question is since its already bored .030 over will it be ok to order a rebuild kit with .030 pistons because I was told you have to match the pistons to the bores for final machining. Is it too late to match them or do I nedd to at all?
