Re: Which Transmission????

Of the three choices I would also pick the 700R4. With the .70 overdrive the 3.73 will be changed to about 2.6 making for a great cruising gear if the engine makes enough torque to be in high gear. My last pick would be the 55 Powerglide. Having just 2 gears really sucks, either too high or too low. I'm not very versed on Powerglides, but I believe this must also be one of the early cast iron models and finding parts for it may be a problem. The TH400 is great behind a 350 or big block, but that's a lot of transmission (heavy and big) for a 230, unless you're planning to put a V8 in front of it sometime in the future.
