Why do you have a C3, that wouldn't be stock with either the 67 or the 93 5.0L....?
But I agree with Nightfire, if you can afford a tranny swap, a beefed up C4 or AOD would make you happy, try Hughes Performance, or Performance automatic....
The C4 would be an easier swap, they came in 67s... the AOD is longer and would require some fitting.
