This may be a stupid question, but would the lower compression, say 12 or 12.5:1 along with a smaller bore of 4.25 or 4.31 aid in sealing and gasket longevity on one of these aluminum blocks? I know 14/15:1 is done daily on the BBC motors, and obviously the LS platforms work well with aluminum blocks in strong driver and race applications. I realize this is apples and oranges, but I'm just trying to get as much feedback as possible and talk myself into pulling the trigger. Realistically, for my power goals, a 400 block with good caps would suffice, but I would really like the peace of mind and the weight savings of the IAIIA or MR1A

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
