Powerglide or 3-speed?
lake_harley:
I understand that the TH200 isn't highly regarded and don't know how significant the modifications might need to be for a 1400# car with 240-ish HP. The website that I saw, Scott McClay's, showed some pretty significant cars but perhaps it's a bit presumptuous to think they're all running TH200 transmissions?
Paul...I'm curious what kind of 3 speed did you run? Did you feel the extra gear was helpful? How was it at the line with what kind of car and engine? What about the possibility of excessive tire spin at the line? With such a mild engine it may not be an issue at all?
FWIW...I have no plans to run a trans-brake, feeling that foot-braking it would be much easier on everything. Is that just folly on my part?
Thanks for the comments everyone.

I agree with low HP and the very mild 3.23 gear a 3 speed transmission would be a help, I'd leave that 200 alone. Parts for it going to be pretty pricy to do any upgrades. I'd just grab a TH350. The savings on parts will likely more than offset the difference in the cost of the core transmission

Thanks again everyone. Funny how after being around all kinds of cars my whole life, and I'm 68, when it comes down to fine points and details I realize just how little I know. :(
Stay tuned for the next noobie question(s) on building a FED. Just to be clear, I do consider myself a competent fabricator & welder and had a fabrication business for about 15 years, which I started from the ground up.

I would try running the th2oo, the torque convertor will depend on the cam used i've used stock convertors, a c3 torque from a pinto in a c4 behind a 289,that would pull the wheel off the line a 4 cylinder chevy 2 convertor in a powerglide behind a 327 chevelle that would ran 13.00s and was the tow car for my race car. the 29x9 on 8" rims will workout well because of the weight would run alot more gear about a 4:10 you will not get too much spin because of the rear wheel weight bias and a 283 doesn't have alot of torque

Paul New....I sent a PM to you about something not directly related to this thread. Wanted to mention it here in case you don't see that you have a new PM. I know I forget to check for them.
