Re: cast iron Powerglide/aluminum Powerglide
 

We raced a 1961 two door impala hardtop SS/X in 1972 283/2bbl with an aluminum glide. We could use either the cast iron or the aluminum unit. When the SS/X record was bombed we switched to a 1962 2dr post car SS/W and set the record with that so I know that setup was legal. The 62 would be a U/SA car now and our best ET back then was 13.70. Probably would run well under the current index even with the stock intake with all the latest technology. The cost of getting a nice 62 would put it out of the dime rocket category.

As most know 1962 was the first year the Alum. P/G was assembly line produced chevy. The 1959 Conv. O/SA that Mark Y. mentioned has a reward trans mount (X frame) like the early Corvettes of Marv Ripes, Hoffman, and others that ran in 70-71, etc. In 1972 the alum. P/G was allowed in the 55-57 Chebbies in S/S with an added trans crossmember. My old brain cells are still kind of working.

Re: cast iron Powerglide/aluminum Powerglide
 

Cars with the rearward trans mount got the aluminum trans FIRST...(per Chevrolet parts
superscession.) Think it being a BOLT-IN might have helped too....

Guessing that '55-'57 Chevies got to use the modern trans when "adding cross-
members" was permitted in SS...think mid 1970's?

Was at '74 Indy...and saw "Marrakesh Express" '56 wagon with 2x4 bbl Corvette
engine...and cast-iron trans....think it was SS/QA class...Trans was "smoked"...
all apart on trailer...with one of the partners in town...chasing down parts.

In 1962, keep in mind ONLY the 327 and 409 ci got the aluminum trans on assembly
line...

....So did the 62 Chevy 11s with 194 cube 6 cylinders. Mine was air cooled, with a sheet metal "scoop" on the torque convertor, and some large, screened holes in the bellhousing area.

In 1974 I bought a cast iron p/g from Marv for our SS/PA 55 chevy 150. Wesley and Red wouldn't allow an aluminum one.

My back hasn't been the same since

Same thing with me- built a 57 Chev for SS in 1974 and had to use a cast iron
PG . Got it from Marv and I remember it was $199 - the convertor was $399

You're absolutely correct, Rory. I was refering to the Full-Size Chevrolet models...listed
in the older Chevrolet parts catalogs as "Passenger Car." Don't think GM uses that
term anymore...
