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

We have had a lot of calls over the years from some of the IMCA guys who have blown up 400 blocks looking for more its kind of a shyty rule as it should not allow a 400 block as it would save the guys some money in the long run.
