Roll Call for anyone with documented 1964 M21 4spd car/ 76X8 engine
 

Anyone own a car or engine , or have documentation for one ?
778 transmission code
76X8 engine code

Step right up , whose next .......

Maybe no help, but here is my original invoice from April, 22, 1964. 3.90 gears, Muncie wide ratio. The dealer had no info on the M21.

I have heard many times about the M21 availability in '64 but never saw one. The stories are about as common as the factory Tri-Power '67 GTO.

found this info https://www.nh-gto.com/GTO%20Engine%20Codes.htm

Bad info , par for the course on X8 and X9 details.

1964 GTO EBAY Ad

Should have added the ebay ad.

Too bad the manifest doesn't show the price for the tranny. Wonder what the price is for it?

:)

What is a "rebuilt title"? Is that like a salvage title?

I'd say yes.
Probably has major parts from a different car. (frame or back halved with another car etc?)
Also probably means the original VIN is not on the car.

:confused:

GREAT Find on that 76X8 eBay car John !

Tranny price was $188.30

Is that the same as the 'W' wide ratio tranny?
