Inliners International Forums General Discussion Drive Train Six cylinder glide vs. v8 glide

Is the low gear ratio for a six cylinder glide the same as for a v8 glide?

I know a six cylinder has a 1.82:1 low and some of the later v8 glides had a 1.76:1 but I am not certain of those available in 1956.

Seperately, will a v8 glide bolt right up to a 235 six?

No, a V ate glide has a different bolt pattern on the bell housing than a 235 L6 so it is not a bolt on unless you use the correct adapter.The stock trans/engine adapter is shaped according to its intended block.Also,there are after market adapters available for later model(better) transmissions from Buffalo and Stovebolt.Check the "INLINER" ad banner.

If I remember correctly the cast iron 'glides were all the same. The only difference was the adapter plate to make it fit a 6 or an 8. As far as low gear ratios they were the same too. Chevy made up the difference in the rear axle ratios. 8 cylinder passenger cars with a glide used 3.36 and the 6's were either 3.55 or 3.73. Optional ratios were dealer installed at that time and standard shift cars and wagons came with a little deeper gearing than the automatic equipped cars.

Greetings . . .

With the number of folks still draggin' with these gizmos I am suprised at how little historical documentation is available for the PG. I have found lots of inidications that GM only ever made two low gear ratios (suggesting 1.82 originally and 1.76 later on) but no inidication when exactly the 1.76 ratio appeared.

But this seems backwards to me based on construction (cast steel versus a stamped steel planetary housing) which suggests that the 1.76 is more likely the original ratio.

The cast iron glide was supposedly built until '61 with the aluminum ones making the scene in '62.

I had also heard 'swap meet talk' years ago that the availability of 1.82 ratio corresponded with the change from the PNDLR selector to the more familiar PRNDL. This happened in '58 I think.

Regardless it appears that GM continued to use both ratios for some time as there are plenty of tech tips indicating how to tell the difference:

hmmm...I beg to differ but...6 cyl and 8 cyl cast iron 'glides are not interchangeable...no matter how you mix and match the adapter rings..unless there's a way of doing it that eludes me.....
