We have a 400 2bolt block that was converted to a splayed 4bolt making 703 hp @ 406ci. This is a drag application. There are always many possibilities. We know that this is not recommended by anyone at this power level but we had the parts and so we built it. That said we see evidence of the block moving around a lot, i.e. cylinders not sealing like we would like allowing blow-by leading to oil leaks. And this block has been poured. Would I recommend anyone else doing this, no way unless you know going in what the end result could be. Call Dart you will sleep better at night. :lol: :lol:
