My stock motor tranny combo is a 307 with a powerglide. I got a mild 454 with nothing special that I want to run in it(my 307 has got no compression left in it's poor soul) just until I can get the parts together for a 496 stroker. And with that stroker I want to run the 200R4 tranny, but for now(maybe 6 months of no track time) will that combo of a mild/stock 454 and a powerglide (stock from the 307) work for street driving (NO, NO track time?)

I plan the 200R4 to be ready when we yank the 454 to stroke it out.

Thanks for your info. Remy

actually the powerglide is one of gm's best transmisions. it should hold up to everyday driving. it was the standard automatic on my ss 396 and a lot of racers use them around here in there 600 horspower modifieds with a little tweeking inside.

My RPMs should be through the roof though I guess right? GALLONS PER MILE as well? lol

Ive been looking at a lot of the signatures etc and havent seen anyone with the bigblock that still had the Powerglide, so I got worried. lol

bb glides have different 2nd gear clutch pads than sb's. i don't think it will hold up many times at full throttle in 2nd. 1st is no problem. tom

In '67 you could get a 427, 400 hp Corvette with a Powerglide. But I'm thinking they were built different than one for a 283 or 327. I remember in HS the ones in tri-five Chevys were pretty weak and wouldn't hold up long behind a stock 265 with a teen behind the wheel.

I had the powerglide in my 66 ss,,Well actually about six of them. nuetral slams are a big no no! It actually came with 396,325HP PG factory put together though.

It will work the BB ones are heavier duty and your convertor is going to be a little loose but the biggest problem might be trying to make the throttle rods work correctly. I haven't tried it so the sb ones may work ok.

The powerglide shouldn't be an issue. With all the thrashings PG's have had from the 396's with no issues I'm confident you'll be fine.

O.K. ,your powerglide should make you a happy man.There were several different glides made ,and even a cast iron one ,I've heard but have yet to see with my own eyes.Most,if not all V-8 cars came with 1.76 planitarys and 6 cylinders came with 1.82's.The 1.76's are stronger and will last a long time behind even a strong Big Block.The planitarys are the weakest link in them but,they should be fine as long as your car doesn't wheigh 2 tons and you don't use a trans break every day.Another other good thing about a glide is that you can order a turbo spline input shaft and run the converter out of your 350 or 400 turbo.You ,yourself can build it to be very strong ,with a call to Summit or Jeggs. In the racing scene ,an upgrade from a powerglide,to another trans,will have you a Lenco or a Bruno.
Some people say,a powerglide is slower in a streetcar,but they also take a whole lot less power to turn.And that means,more power to the tires.

BORDERBUM,

Here is how a P/G works!!

You leave full-tilt and low try's to catch up, it catch's up and it shift's into high and again try's to catch up UNTIL it does!!

It's like a four-speed b/c it is always trying to catch up!!

DAMN good tranny in the ligher car, imho, for NO more that I know about them..

I really appreciate the information, Im glad that the powerglide will work for now. I knew that they were used in racing applications and mudd trucks etc, but I was unsure of a big block application, thanks for the input on the 396 cars coming out with them, I did not know that info at all. Thanks !! Remy

All you really need to do for many street applications is to just replace the OEM cast iron high gear hub with a steel one, and do some valve body mods. A better input shaft is not a bad idea either. If you decide to tear into a Glide and need some help just let me know and I'll do my best to guide you along.
