The engine is a coasthigh motor..all forged hbeam rods stud heads..so I think the motor is good ..I haven't had much dealing with a super changer..I'm thinking of taking it off and going turbo..

I have a Procharger D1SC with about 30k+ miles with only a few problems along the way. Is that a stock block 347? If so that might be your weak link.

Blower is no problem, stock block will be the fuse. Blow thru won't be AS street friendly as EFI, but properly tuned, you should be ok. Depends on your use.

The block is a R block so not really worried about the bottom end ...it made mid 600hp on 14 lb ..I have heard of them being hard on the main bearing because of the pulley setup pulling on the crank.
