The difference between a Standard SB chevy and a Z setup is that the harmonic balance is a larger diameter than the standard balancer. The timing tab is located further out to allow for the difference.

It's 8". That's the same for all 69 and up 350s and 400s. Although the 400 balancer is different since they are balanced externally, they still have the same 8" diameter as the rest. So that theory doesn't hold water.

Not 302 specific. Only 8" balancer specific.

They are easy to find. Chevy used the 8" balancer from 1969 to 1980 on 262, 267,307,350 and 400. They made "a few".

Are any of you interested in buying this or just discussing it?

I think we're simply trying to make sure none of our beloved fellow members get bent slap over the toolbox and slammed up the keester. We'd do the same for you.
 
This one. Sounds right, but hey, I'm not familiar with Chevy stuff anymore.

I have an 1967 HM block 327 sitting on an engine stand in the garage, I will get a pict and measure

The difference that I see is compared to the OP's picture is the tab is inverted to set at a wider circumference. And for the record i dont have a pony in this race

Who said they were the same? There were lots of different diameters. All I said was that Chevy used the 8" balancer on a wide range of engines from 69-80 and that's a fact. The tabs for the 8" balancers also came attached different ways. Some, with the weld on tab facing toward the crankshaft, such as the OP's and some with the weld tab facing away from the crank. Both types were used for the 8" balancer. There was no rhyme or reason as to which you got. There are several just like the OP's on Ebay right now. They are also available as a new repop for like 49 bucks. This "discussion" never included any balancer prior to 1969, OR the later 305 balancers that were smaller in diameter and sorta "fat" looking. All "I" was speaking of were small blocks that used the 8" balancer.....and there were literally MILLIONS of them made and they all used similar timing covers that the OP is trying to sell.

PITA maybe, but maybe a mod could split this discussion from the for sale ad and create a discussion thread elsewhere as this seems to be a topic people want to discuss.
