Is there any advantage besides weight from a cast iron powerglide vs. aluminum ? Picked up one of each this past weekend.
alot easier to find parts for a aluminum glide...most of the drag racers are using them...in 1 shape or another.
Aluminum 'Glides are way better. Simpler, stronger, and the easiest auto trans to rebuild. The iron ones are a *****.
If you get an iron Powerglide, make sure you get all the parts. V8 applications used a steel adapter ring on the front of the bell housing, which was not required for six-cylinder applications.
if you plan on hammer'n it, get a blanket or ****ter sheild for the bell housing, if you like your feet.
The six cylinder cast powerglides did have a cast adapter and were different from the V8 units. The starter location was different, so the bellhousing and adapter was too.
The early aluminum PGs for 6s and 4s are air-cooled as evidenced the large screened holes in the bellhousing. They do take the same guts as the V8 models with the solid bellhousings. I have one in my Old Roadster. Tough little box in a T bucket.
The cast iron units have to weigh 3x what the aluminum ones do. I've humped a couple in and out on the driveway and swore off them for good. The good old aluminum ones always worked for me and were easy to fix too. Bob
62 was last year for CI P'slides. They were used only with 235 six and 283 v-8s. The 327 and 409's used the aluminum P'slides in 62, as did the 153 fours and 194 sixes. 1963 had no CI P'slides.
Might be, what year is the transmission? Do you have the V8 adapter ring and flexplate for v8 too? What engine was it intended for? Might find an id plate on it that will tell you what year and engine it was made for.
