This 11 inch 168 tooth flywheel has been cleaned and surfaced. It is ready to be used. The part number on the back is 3973456N and the date code is B/1/9. I belive that is Feb. 1st 1969 $175.00 plus freight and 10% gets donated to the Supercar web site. Anybody have any interest in a 074 aluminum big block open chamber head that looks to have never been used? Please e-mail at [email protected] or call me at 714-962-7650 if you have any questions or if you want pictures e-mailed to you.

What is the casting date on the 074 head?
Is it complete?

I have a 456N flywheel on a 454. It has the large cast counterweight near the ring gear. Did they use the same casting for both internal and external balanced engines?Does yours have the counterweight?

Thanks,
Eric

Shows how much I know. I thought this part number was specific to the internally balanced 396 427 motors. This flywheel does not have the large counterweight. The aluminum head is bare and has a 1972 casting date. I attached a picture.
