I ended up trading an old pickup for a 91 Formula with a TT LS. I'm pulling the engine for my 95 Z28. I'm expecting about 900whp(conservatively) and trying to decide on what transmission to run. I have a couple 4l60e's and TH 400's laying around. I don't think the 60 would be sufficient so that avenue I think I would trade up to an 80. Any input from someone who's been down this road?
