As far as transmissions and gearing, you can drive yourself nuts with the formula. What do you plan on doing with the car. Are you a long hauler (Highway), do you just cruise the streets? Your car is cammed like mine. I have no issues with the TKO 600. I've had both the .64 and the .82. with a 27" tire. My motor is cammed like yours also. If I had one complaint it would be the large rpm drop of the .64, but 2200 rpms on the highway was quiet. .73 would have been ideal. I'm more concerned about my gearing for the autocross ( I run tight courses in my area, and will try 3.55 rear gears. So, you see what I mean, it really depends on what your going to do with your car.

I want my cake and I want the ice cream to go with it! My car is purely a street car and all I want is insane roll on power and a cruising gear.....thus I have been looking at the T56 tranny option. I know it cost more but if I can get more aggressive gearing than what I have now and still have a 6th gear for interstate / faster back road cruising then I think I would be really pleased with the car. I have looked at all the .82 TKO-600 combos and the 5th gear is too short when you get into 3.91+......I also don't like the idea of the .64 4th to 5th rpm drop. This new cam Brent specified and all the other freshening that is taking place should make a world of difference.

As for the rearend, a 3.73 to 4.10 is usually the sweet spot for these cars. Going from a 3.27-3.31 to either one of those ratios will be a dramatic difference.

I have no issue with using a twin disk and I'm not willing to save a few hundred dollars to deal with chatter ect. I think you estimated my HP to be around 550HP with this new cam so while it isn't big horsepower it may future proof the car for future upgrades. I will take a look at the McLeod RST.....I believe this was in my previous 03 Cobra.
