Moving on up.....
Leave the converter, get that 28 inch tire on it and just see what that gets you.
There's other gear ratio's available for a Th400 other then the std 2.48 1st, you may want to think about that too. If you can get the 2.75 or whatever the higher one is.. it might be worth a shot. That along with the lightened internals while you have it apart and I bet there's your 60 foot back, and another good bit.
The guys I know with fast fast low power auto cars are all running tranny's with the lightweight internals, they don't take alot of power, but when a car's in the cam only power range and light, it holds up just fine.

Im not sure on the rpm. Im gonna say around 6400 ish maybe??? Ill have to have dlove pull a log for me and look. Im running the 230mm Circle D 5C converter. Its flashing at 4400 right now. The 5C i had last year in my 4l60 would flash at 5k. The cars getting better in the 60ft now. I know 1.47-1.48s aren't the best but its better than 1.50s lol. When the weather breaks im gonna throw the 28s on and see what happens. All else fails turn the rev limiter up!!

Ya no trans brake. All that will come next year. Its a little tight but not enough where it really bugs me that much. Im sure im leaving some on the table with it, but id like to try a few other things first before i pull the tranny. Over all im happy with how the cars running so far this year. especially for the wonderful air we get. lol
