Is anyone running a powerglide in a 50's caddy?? Was thinking of running a 350 but i have a powerglide in my yard
I wouldn't go through the work and expense of adapting a more modern transmission just so I could have a two speed automatic.
Model A John and Heathen are correct. Just because you have a P/G in your 'yard?' (a questionable source of reliable mechanical devices) doesn't mean that it's prudent to spend the time and money necessary to create an adaptor so you can give up two speeds, and have a transmission that will not serve you well for general driving or on the highway. Find one of the ubiquitous 350TH trannies out there, and spend your 'adapting' money on that - may turn out that just a plate is necessary after you sit down with your tape measure and a quick cardboard template of your block bolt pattern and compare it to the transmission bolt pattern. Hit the salvage yards, you'll be wanting to measure all the GM 350 transmissions - Chev, BOP, Cad, see which one might cause you the least problems. Be mindful of starter mounting/location also. Most late trannies have a bulge for the starter snout, but no mounting holes. Best of luck.... dj
If by 350 he means chevrolet then the powerslip is a bolt on no adapter needed. Unless it isn't a chevy ******. Might have to change to an earlier flex plate at the outside most. A Turbo350 is a better option for sure. Or you could go the 472/500 route with a Turbo 375 or 400. You can still find good ones out there and they are not a real expensive motor to buy.
adapting a Chev/GM ****** to an early Caddy engine requires more than a simple "plate" to adapt the case. The old Hydro's torus was a two piece affair, one part of which bolted to the crankshaft flange directly, no flexplate......so to adapt a newer trans also requires adapting a suitable flexplate and, as previously mentioned in other posts, provisions for a starter.
