I.D. Powerglide Flex Plate

[Wayne M.]

I have the one shown below and am trying to put a part # to it. I realize it is not Corvette (who uses blue paint ? Buick ?) but it seems identical to one on eBay, #3868806, (link below)which shows in GM parts books as for '65-6 Pass. w/396; '66 Corvette w/427, P.G. [not many of those produced]

Notice the upper quadrant on the engine side missing paint. The part # for '67-8 changed to 3899668, with the center hole (crank flange) increasing by 15 thou.

What flex plate did small blocks use ? This one has a 14.25" O.D. ring gear and 168 teeth.

And why don't the P&A parts books show a part # for the ring gear (alone) ?

Wayne, the original plate I took off my 67 327 was approx 12 3/4" dia. with 153 teeth and had chev. orange on 1/2 of it. I did an earlier post on paint markings on it & the TC near the beginning of Jan. AL

C1 Corvettes with Powerglide used the predecessor to the 3868806, the same flexplate also used for 1966 Corvette big blocks as well as other applications. These were nominally 14" flexplates.

All C2 small blocks with powerglide used 12-3/4" flywheels.
