Flywheel question
Does anyone have info on the application of the following flywheel, which is 14" and 168 tooth:
#3988795, also has the word "NODULAR" cast into it on the block side, casting date L08. Thanks! :thumbs: |
'66-'74 big-blocks (except L-88) and '69-'81 small-blocks (except ZR-1) used 14" 168-tooth flywheels - it's probably one of those. :thumbs:
|
I went out and pulled all of my 168 tooth flywheels (about 15). None of them have that casting number.
Does it have a bolt pattern for a 10.5in clutch or a bolt pattern for an 11in clutch? |
Thanks a lot for the information. :cheers:
Is there an easy way to tell which bolt pattern is on the flywheel? Thanks again! |
For a 168 tooth (14in diameter) flywheel with a bolt pattern for the 11in clutch, the bolt holes will be near the perimeter of the flywheel.
For a 168 tooth flywheel with a bolt pattern for a 10.5in clutch, the bolt holes will be about an inch away from the edge of the flywheel. There were some flywheels made with dual bolt patterns. |
The bolt holes are close to the edge, much less than an inch, and there is a single bolt hole pattern. So this must be for an 11" clutch.
|
Yep, sounds like it to me.

Hi,
Are you sure that it's not 3988759 ??? That part number is listed in my Chevrolet passenger car parts catalog as fitting 66-69 passenger car with 427 and manual trans. RON |
