Lost a lot of performance
I am slowly taking the streetcar from running 11.70's back to basically stock. I have not changed anything on the engine yet other than the carb. I took the th400 with race converter out and replaced it with a 200r4 OD trans and stock 12" converter. I also changed from a 750Holley DP to a 750 Holley vacuum secondary carb. I did not think it would lose that much performance. Seat of the pants feels like I lost 100hp. Just very surprised.
Guess the $800 race converter was worth every dime I paid for it.
