I've looked through alot of the posts and seen that a 200-4R would make a good addition to my 70 GTO convertible, mainly from the ease of vehicle conversion. There are many 200-4R builders out there: Art Carr, Bowtie Overdrives, CK Performance, Monster Motorsports, Level 10, Performance Transmissions (Raptor), Phoenix Trans, and TCI Performance. I was wondering whom all of you think is the best from a durability and cost perspective. I am interested in a street trans (400-450 HP), not a racing one -- other than the occasional "stoplight" race! I would appreciate any opinions and comments you guys have.
