I've agot a C6 behind my 446 cube FE engine in my 67/69 F250. The tranny was rebuilt less than 10,000 miles ago, and it runs well. I'd like to get the shifts a little quicker and the shifting RPM at WOT up around 5500rpm.

I know very little about transmissions. Any suggestions on how to optimize this tranny? It's a 4600lb truck, with approximiately 500 HP, 550 lb-ft of torque. It's a street/strip 3/4 ton truck, that still needs to act like a truck. Yes, I don wnat to have my cake an eat it to :-) I've paid twice for both.

I just got my B&M truck Megashifter and a TCI Torque Converter that should give me a 2200rpm stall. Per their reccomendations that should be the best TC for my application.

Any advice on optimizing this C6 is greatly appreciated.
