End of the year HP averages

Turboglides did come in 283 powered cars starting in '57, not sure when they dropped them, maybe '61. A three speed was never factory installed behind a 283 that I remember but some late 50's pickups came with a 283 and the 4 speed hydro, the sedan deliveries were considered trucks so that's how they were able to use the hydros.
350 transmissions were not introduced until 1969, no three speeds for the 64's, the '65 big cars used the turbo 400 for the first time behind the 396. The turbo 400 was used behind small blocks in '68 big cars and some '68 pickups and of course in Vettes for several years. Ironically the '66 Chevelle 396 auto cars were powerglides.
I'm pretty sure Tarrances car was a three speed.


No documentation for backup but the way I remembered it.

three speed automatic in late 50/60s was sedan deliverys only those panel truck looking things that's the way I remember it hope im not given my age away

Sedan Delivery has 4 Speed Hydro in 50's
All others were Powerglides
Hence the popularity of the Sedan Delivery Wagons.

I am even older than you Mike!

I've never seen a 283 car with a 3 speed auto in it, not counting turboglides which were 3 speed autos. The FIRST smallblock car that I ever saw with a 350 turbo in it was/is a 68 Camaro 327/275 bought NEW by a Bracket Racer in N.J. and he STILL has the car.
To my knowledge you couldn't get a 4 speed behind a 6 cyl. in a Chevy II but you COULD in a Camaro. I've owned two.

Wow, if Steve’s car was indeed a 3 speed.....it’s even more impressive.....always remember him rocking in the seat during the gear exchange...

I am pretty certain we sold Steve all of our GM three speed stuff (well used) when we went to the Nash 4-1 trans in early 1977.

Correct me if I am wrong. The sedan delivery did not come with the 4 speed hydro. NHRA declared them to be a light duty truck, and allowed the hydro to be run in them, but the trans came in pickup trucks.

as far as the turboglide i HAVE ALL THE DOCUMENTATION you need ... was what i was showing to bruce and garcia to get it approved LEGALLY .... which lasted 11 months before they gave three speeds to all the other who DID NOT COME WITH ONE !!! in fact it was the documentaion that endeared me to WAYNE in division 5 !! LOL

end of story ....
captain

i dont wanna discuss the intake

Did anyone else notice that a turboglide 283 had a larger pilot bearing hole then a powerglide or stick car {just the hole size } or did I get the only one ever made ? A normal sized pilot bearing was too small for the hole in the crank but I did find an aftermarket one that worked for a stick trans setup. I did break the crank but that was my fault
