well, I'll chime in with a bit of first hand knowledge, I put a 2500+ miles on mine since I got it in July (world block'd aluminum 427) and have had no issues. We beat it vigorously on the dyno on 2 occasions. I haven't had ring seal issues or anything out of the ordinary. It was nice that the off the shelf pan, timing covers, etc all fit it too, and since it wasn't a tall deck it still fit under an SS hood even with a super-victor intake (barely.) Headers still fit too, although they did sit a bit higher than on my old motor. -Dan
