I have a 3000 converter and I shift about 6200. How does it launch. What kind of ring and pinion you running.
I have a 349 with a 9-inch 389 gear on nine Hoosier slicks /26 my best 60 foot has been a 1.6 but mostly it's around 1.7 a best et 7.606 in 1/8. 90mph
Your converter stall speed has nothing to do with how far the RPM drops between gears, This would be caused by transmission gear spacing. Are you running a stock ratio C4 in your car or does it have a wide ratio gear set?
My C4 is stock,, i was told if I went to like a 4500 stall the rpm would not drop as much .? Not sure... maverick 306 I ran 389 gears and 430 gear ,my car had almost the same 60 foot,,
The only time a Converter would effect the RPM during a gear change would be if the Converter was So loose that it is slipping during gear changes, if this is happening it will kill your top end speed!
