1967 Z28 automatic?????

[markjohnson]

Gosh, I'm already hating myself for responding on pg.3 of a disputed '67 Z-28/Powerglide but I'm having a good time tripping on P.C.P. right now.....so why not 'til this wears off. I'm sure special combinations could be "special-ordered" by GM exectutives, but this was usually just something like an unusual Paint request or something. Does a Holley List #3910 for '67 Z-28 applications even have a kickdown provision? What about vacuum fitting and line for the transmission modulator? What kind of radiator would have been used so it would have a transmission cooler? I don't even need to mention what a dog this car would have been with that long-duration solid camshaft and a stock convertor'ed Powerglide. It would have been embarassing slow and a laughing stock! As far as this Vietnam Vet theory.......such a veteran would have been persuaded to purchase a nice Bumblebee stripe'ed '67 automatic SS350.

Sometimes rare doesn't mean desirable.

If it were only a convertible.......Hmmmm?

Since SS350-Automatics weren't available for '67 cars either, anyone wanting a performance engine w/ an auto would've probably been 'steered' into an L35/M40 car!.

????? What do you mean no SS350 automatics?

in the late 70's I used to work on a customers documented RS/SS 350 convertible, and it had a power glide in it. He was the second owner &amp; he had all the original paperwork for it.

Why didn't Chevrolet put the TH400 in the Corvette in 67 rather than continue with the PG as the only automatic choice? Oldsmobile offered the TH400 in their 442.
Was the TH400 offered in the Ss396 Chevelle and SS396 Camaro?

yes, my understanding is the trans tunnel on the 63-67 was not large enough for the t-400 ... 68 &amp; up vettes had the t-400 though

Anybody that knows anything about automatics, already knows why they did not use an automatic. You would have to have a min.3200 rpm stall converter. These engines with the 4-speed are not even driver friendly, they are a handful. And mine came with the rare scca prototype chambered exhaust. Roger

Chevrolet didn't get TH400's sorted out for high performance applications until 1968, most notably the Fred Gibb COPO 396-375 Novas. In 1969 though, you could pretty much get them across the board in everything to 396-375 L-78's all the way up to the King......the '69 ZL-1 427 Camaro. It's also kinda funny to note that if you wanted to go fast with an automatic tranny in a Chevrolet application, companies like Wilcap and Art Carr sold adapter kits to put a Chrysler Pushbutton Torqueflite behind Chevrolet cars. It even came with a neat console/tower to mount the push button panel between the seats in the stock console area. I know of an aluminum front Z-11 car locally here that ended up with a Torqueflite after breaking many 4-speeds.
