oil pan stock 1969 z28

tough to find,  need height specs
thanks in advance!

Original production line installed 69 Z28 oil pans are getting tougher to find, lots of later issue pans around, but they have a small size dimple on the front of the pan just behind the front seal. The later pan was availiable under #360450 from GM, but pretty sure it’s discontinued. Corvette L82 pan from 74-77 is the same as 360450. Look on eBay, there are usually the late production pan with the dimple listed, but despite what the ad says they are not correct.
Also FWIW the production line windage trays are different too, with just a round hole where dipstick goes through, 1971 and up have a oblong hole.

The height/depth of the Z28 pan is the same as any SBC pan from 69-77.

I measured a original 69 Z pan and it seems like it’s 7&9/16 depth with a level on it parallel to bench surface.

Thanks guys for the info.
what a pain in the butt .
Fortunate to get an NOS pan never used, paid through the nose, but gives me piece of mind knowing it's correct too.

[WaltZ]

Out of curiosity, what is the part number on the pan ? I have a fairly early NOS pan I'd like to compare it to -

sorry Steve, don't have that info , the best I can do when it's back at the shop tomorrow, I will take pictures and post.
the machine shop believes it was possibly manufactured in Canada.

That's a distinct possibility, the 360450 that I purchased many years back for my '68 build was marked "Made in Canada" on the box if i remember correctly -

FWIW- I am Pretty sure the 360450 pans ALL have the dimple, I used a lot of them at the Corvette Shop I was at for 20 yrs. I have also body worked the dimple out with a hammer and dolly as well to make it resemble the production 302 pan, but the 360450 pans all take the big front oil pan seal, so it is not perfect but very close.
Hope this helps.
Mike.

Pic of the oil pan "dimple" and the 2 windage trays as forwarded. I guess I'll have to dig my 251 out and compare it now - I don't remember the dimple being on it, but I'll scope it out.

Steve

Thanks for posting the pictures Steve. The bottom 1 also shows the incorrect baffle with the slot, the upper 1 is a Production line installed baffle.
Cheers. Mike
