Is the 2004r the answer?

[Dan Sherwood]

I've got a 3700lb 69 camaro with a 560hp 406, and the occasional 25 shot to hit the 11.5 mark at the dragstrip and occasionaly will get to a road course with the car as a back up to my 67.
I currently am running a th350 with a gear vendor setup which works very well in the 1/4, decent in the road course when the temps are below the mid 80's and ok on the street. With the 3.73's however, it still turns too many r's on the freeway at 70mph, and does'nt help the mpg either.
Debating on an od trans, (putting the gv behind the bbc on the 67) and trying to keep the weight down, while possibly improving the 60fts. Wondering if the 2004r is the ticket to get where I want to go? Who makes one to fulfill all my requirements? Lockup vs non lockup, and convertor suggestions???? Thx!
