Chevrolet / GMC 292 6-cylinder Flywheel. This flywheel has 1/2" bolt holes and one 7/16" dowel pin hole. It will ONLY bolt to 292 crankshafts. It will NOT fit any other GM engine. This flywheel has had the disk area resurfaced to like new condition. It has a 168 tooth ring gear in excellent condition. Casting number is 973458. Date code is D237 (April 23, 1967). Weight = 27 pounds. Asking $120 Can. ($90 US) plus shipping.
Interesting note on your 292 flywheel that I never knew before. Good thing you listed the casting date. I looked it up in my Hollander interchange just for fun.
1966 and older 292 flywheel interchanges with small block. 283, 327 etc. up to and including 1966 except the dowel pin pilot hole has to be drilled out slightly to use it on a small block.
1967 flywheels like yours are when it became unique to 292. I always thought it was unique for 292 from when they began. At least, so says Hollander.

Pretty specialized item! However being the weirdo that I am I have an application for it. I have a tired but eminently restorable Canadian built 1967 GMC shortbox-stepside 4x4 with a 292 that was built on May 5th 1967.(One of 33 of that model according to the boys at VVS.)
Once I get around to it I will probably wish I had a good flywheel so.. PM coming your way.
I'm have an early 6-counterweight 292 crank in my low-deck six. I think they only used them 63-64 in the U.S. but up to '66 in Canada. I'd have to check when I have the time to verify. IIRC my builder made the engine neutral balanced & used a small block flywheel. Trucks can have clutches to 12" in some 292 applications.
Attached are some AMA specs for a 1967 K10 4wd. Base price was very important in marketing and so with the 250 as late as '67 they still came with crash box 2.94 low 3-speeds with 10" clutches, otherwise a 4-speed or a 292 came standard with an 11" clutch. On C10 2wd models the fully synchronized 3-speed was optional with the 250, standard with other engines. The 2.94 low 3-speed was replaced in passenger car lines for '66 with a fully synchronized 2.85:1 low 3-speed.
I just learned something. The crash box 2.94:1 low 3-speed was the only 3-speed used on KS10 (6-cyl) & KE10 (8-cyl), EVEN with the 327, in '67. The M20 4-speed was a H.D. Chevrolet 465 with a granny gear with something like 6:1 low. Those had a shift ball that said: L 1 2 3 in the H-pattern for the forward gears. Curiously the 327 K10 that year was 3-speed only.
Even the 68 still had the crash box 3 speed Cam. I just converted a 68 GMC 6 cylinder to a Saginaw syncronized 3 speed for someone last year. Not a bad swap actually but the linkages are different. Thankfully he had the correct linkage from a later model 3 speed pickup. That would have been the worst part of the swap without those.
