Default Powerglide 427

I was reading literature on the 67 Corvette and was surprised to see that Powerglide transmission was offered on certain 427 engines but not on the 327/350 engine. That makes no sense to me. Why would Chevrolet offer the PG on the bigger more powerful engine? Just how rare was the 427 PG in 1967?

Several:
Idle speed, lack of low speed torque and low vacume being some.

Note:
The stock alum. case PG is good for up to 400 hp. The Turbo 350 on the other hand I've never seen behind more than 300 factory hp. Makes one think.

Seems like the production number was only a couple dozen.

They were killer street race combos! Hooked better on the skinny tires

I once saw a Blk/Red coupe 390hp PG, around 1986, for sale, out in the country, in Puerto Rico!

Yep, 392 with 390hp and 207 with 400hp. I rather like the Powerglide and hope to have a drive someday with a 427/Powerglide. Must be quite an experience with that low-end torque.

The way I understand it, the PG was the only AT in town for BB power until GM came out with the Turbo 400 in the C3.

Just try to find a used aluminum case PG in good shape. The drag racers have used 'em all up! Stock, they are very strong, and the hot rod aftermarket now produces even heavier-duty versions to meet racer demand.

I always liked being able to push or coast-start a PG car.

Until the accountants removed the rear pump in the late 60's or early 70's.

I'm not sure but I don't believe any aluminum case PG's had a rear pump. I think that went away sometime, '58-'60.

Corvair PG (Yes, they are a tad smaller) had one at least in '66. Drug one home and turned over the engine while it was on the end of a rope.

The Corvette Center in West Hartford, CT had one on their floor around 1991. It was a 400 HP 427 with a PG. I think it had A/C too.

OK, just a comment that might be off-topic for the thread. But here goes. I have one of the 1,725 1967 Corvettes with the 327/300/Powerglide combo. Rare, yes! Desireable, no! Runt of the litter. No one wants them: any market guide discounts it by 10-15%. And I find that strange as I very much enjoy my car. But it's mine. What the heck.

Awe, the older we get the more desireable they become.

Many older collectors backs have worn out with age. And if you know what Im talking about you know the WORST thing for and old back is pushing down a stiff clutch pedal.

I am currently restoring a 67 elkhart blue 427/390 with a/c and powerglide. It was purchased new in Charleston, SC, backed into a block garage in 1982 and left until we pulled it out last spring. We had to cut small trees away from the door to pull it out. 38,000 miles with a great tank sticker still in place. mice had destroyed the interior and the 1st edition owners manual. also have a friend restoring a red/red 400 coupe with air and powerglide. this car appears to be a COPO car looking at the tank sticker. Both cars are 6 to 8 mos away from their first NCRS outing.

Default I Think The Big Block Cars With The PG Are Great!

In fact, when I retire in a couple years I will probably look for one to go
with our 1966 PG 327/300 HP Convertble. Keep in mind that many of these cars had other options including power brakes, power steering, and AC making them great road cars.
On cruise nights we love our 1966 because it is much easier to drive than an older car with a heavy clutch. The factory AC helps out too!

My 58 is equipped with a PG and I really like it. Great in traffic, takes the stress out of crowded urban driving. My wife says it is easier on her leg (back surgery last year). I think we'll call ours a "keeper".

Regards,

Fred
