If not for IMCA production block rules, it would be a no brainer to go with an after market block. Unfortunately, that rule prohibits any aftermarket block including bowtie blocks.
From what I'm hearing I can build a 400 production block based 377, but shouldn't expect more than a couple of seasons out of it at most. That sux!
Guess I need to hunt down a good 4 bolt main 350 block and build a good SOLID 383. Anyone have one available?
Thanks for all the replies folks
