cast iron Powerglide/aluminum Powerglide

In what year did NHRA start allowing cars originally equiped with cast iron Powerglides to start using aluminum Powerglides?

Guessing, 70- 71...I know were legal.
Maybe after they took away the Hydros from the Sedan Deliverys ?

Thanks Mark, I figured you would know.

Its neat to look back at some of those old pictures of the sedan deliveries, but I still can't figure how NHRA ever let that tranny be used in a passenger car.

When they did away with Hydro Al glide was allowed. 70 I believe. Hydro was a car trans in Pontiac and Olds used also in 1/2 ton pickup. Since Delivery appeared in Truck catalogs guess someone who played the rule book game got them to allow cross breed.
Vette motor wasnt available in Delivery either. Lucky for many the vette motor WAS available in 2 Dr. Wagon. Tin snips, change the tailgate and add a rear seat and Presto a legal stocker.( trans change too.)

I do nt think you could use a aluminum powerglide in a car that came with a cast iron one in 70 or 71
