Inliners International Forums General Discussion Blown and Injected Hacking together EFI on an Pontiac OHC Six

X2. A mere 60 mph in direct with the converter locked is 3400 rpm . A 5000 rpm 3-4 up shift would happen at 88 mph IF the converter was locked up, unlocked 3-4 would happen at a lower speed. One thing that has happened to me when I changed to a higher numerical gear ratio in the rear end the car felt slower even though I knew better. Has this happened to anyone else?
