You can get a good flywheel(flexplate) from summit or jegs. I actually think the price for the one we got was about the same as a stock unit. The one I got was from Jegs. The converter was a Torco. Needless to say never bought another from them. A couple hundred bucks ended up costing almost 2gs. I dont know if anyone has any luck with them but the one we got was junk. Oh and the tranny is behind a 427 big block and everyone knew that. The tranny builder sold his shop a little after he built ours. HMMMMM wonder why. So I ended up taking it to a friend that owns a tranny shop here In San Antonio and have not had a problem out of it since. And to top it off he put a 1yr warranty on it. Needless to say when it comes to a tranny I can be a little picky now.
