Remember that the 283 is not running quicker just because of a horsepower change. NHRA finally allowed the three speed which should have been legal all along.

The Turbo 350 was available from the factory after 1964 and found it's way into a lot of combinations. The factory didn't release all information to NHRA and there are some things that NHRA just accepted.
Can a six cylinder chevy 2 use a four speed stick?

I raced a 283 for a few seasons in a wagon similar to Captain Jack. I know either in the late 50 s or early 60 s Chevy had a turboglide but I am not sure it came behind a 283. Every 283 I have seen had a PG behind it ...maybe Billy Nees or Mark Yac can chime in....When Steve Tarrance was kicking Azz with his 6 cylinder Chevy 11 he was running a 4 speed...

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!

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.
