Well I just ran accross my notes on the 2 340s I built, and BOTH engines were dirt late model engines, and BOTH blocks were 360 blocks with callies spacers, so that answers that. That kinda sucks. I knew I had them speced at 340" and they are, just older 360 blocks. Sorry,

Someone needs to do this then. The fella on here who specializes in seals and gaskets should try to get the ball rolling maybee?
