Robert, It'll hold up if you build it correctly. My 428(torquey) with a power shot Nitrous Oxide kit made 50 trips to the track and then retired to the street. The guy that bought it from me still drives it with no problems with the BOP ten bolt. I would get on the phone with Summit and order the Eaton carrier and the complete installation and bearing kits. There are no C clips in the BOP ten bolts so you are already better than the Chevy rear ends in that respect. If you want to spring for plane fare and lodging for two I'll build it for you.
