I'm not really sure if most of you understand that. with coated bearings, ARP studs and cap-screws, all forged internals, high volume/pressure oil pump, and having them professionally installed there shouldn't be any issues at all. the block i have is a strong block as well. I did things on that engine i knew I shouldn't have, like not rebuild the bottom end, not have the block magnafluxed, not change the cam bearings. all things I should have done after that engine was in a front end wreck. I wasn't really surprised it blew, more so how bad.

I fully understand it. And there will probably be a change in the block between the 383 and 396 since it needs to accomidate a longer stroke. I would bet that it needs to be clearanced more. You say your block is good- did you check the core shift? Did the piston carve up the cylinder wall at all when it went?
I still don't understand why you don't just go to a 400 block and save all the money you'd have to spend on extra work to make a smaller engine. Especially since this existing block needs to be bored, honed, etc.
To each his own, and I wish you the best of course. Just sounds like you are taking the long road.
