67 Z 28 Crankshaft

[Eriehunter]

Howdy !! First time poster here..

I have a 67 Z 28 crankshaft it has the right casting number and the "notch" that identifies it as a Z 28 crank,  anyone have any idea what it may be worth?

It is in decent shape, probably will need to be polished at a minimum but may need to be turned.

i say between $200 - $800 depending on the condition and the buyer. jerry macneish can probably tell you more about it and point you in the right direction

Thanks

Are the last 3 numbers on the casting 822?  This crank is quite common and was used in 283's as well and has the notch.  They are not a high value crank.

so a 67 mo 302 crank is the same as a 283 steel crank? then that would make a 68 302 crank a one year only piece seeing how 68s were large journal and 69 was a different #1178.am i right would like to get the facts right for future reference.

It is a small journal crank, I don't have it right in front of me,  I was under the impression that the 822 crank w/o the notch is a 283 crank,  the notch in an 822  meant it is a 302 crank,  as only those had the notch.  It was part of my dad's parts collection and he had lots of performance stuff from the era and was grouped in with the 69 z cranks in the "parts pile"

I would say any ONE of the '68-'69 large journal Z/28 cranks in the "Z/28 Crank Pile" would be worth more than the '67 Z/28 crank.

I think there would be some differences between 283 and sj 302 cranks due to counterweight balance differences. Nothing significant that a good balance shop could not fix. The snout on a 283 is not always drilled for a balancer retainer bolt so that is something else to consider.

Also, the 302 crankshafts were tuffrided for high performance applications.  The 283 crankshafts were not tuffrided.

After looking in the "parts pile" I have what may be a 68 z crank.  I'll do more research and see what it is.

[RAfbody]

I have pulled 822 cranks out of 283 engines and they have the notch but are not tuffrided.  Here is a picture I took of a 302 crank between 2 283 cranks.  They are all 822 cranks.  Notice the counterweights are darker on the 283 cranks from staining.

How can you tell if a crank is tuffrided ?

Tuffrided crankshafts have a dull gray finish.

The 6764 is a nitrated crankshaft and the correct and only crankshaft for the 67 302ci. However, the 8522 is the same in appearance and will work to built a 302 motor.

my interchange book shows for 67 302:
3917265 part number
6764, 3876764 casting numbers
