Early Z/28 oil pans

[Lynn]

As part of the discussion on another thread last week, there were questions about the 67, 68 and 69 oil pans. See: https://www.yenko.net/ubbthreads/showflat...e=0&fpart=4

Part of the discussion centered around an NOS pan I had for sale on ebay, part number 360450. First, I found out my pan is still available from GM. Guess NOS doesn't necessarilly mean no longer available. Anyway, we never received a definitive answer as to whether all three years used the same pan. So I decided to ask Mr. Definitive himself, and sent the following to Jerry M.

Hi Jerry:

Lynn Bilodeau from OKC here.

Did all the 302's use the same oil pan? Was it part umber 360009 for all three years? I know they all used the windage tray.

Last week I compared a known original from a 67 Z/28 (car is long gone, having been totaled in the 70's) with a 465220 and it sure looked different.
The 465220 looks identical, except for the paint finish, with the currently available 360450 pan.

We had quite a discussion on the yenko.net board, but no conclusive answers.

Thanks in advance for any input.

Got the following reply:

"Lynn,

There are actually three 302 pans for the three years. The 67's use a
2-step pan, early 68's are not quite the same and later 68 and 69's use
the current one available from GM. Only difference from pan available
now for 68-69 is the front seal thickness.

Jerry"

So, we already have a post of a picture for a 67 Z/28 pan, and know the late 68 & 69 pan look the same as the new ones, does anyone have a picture of an early 68 Z/28 pan?

We had an issue with some dents in the original oil pan of our '69 Z28. The biggest difference (we found) between the original (circa 1969) and the new GM casting oil pan (circa 2004) is the side molding indentations on the pan.

I know this is sort of off topic, but pretains upon reference.

Lynn, the pan that came with my 68 Z (build date Jan 68) looked so different than the pics I was seeing, that I just figured it was wrong. From what Jerry told you, maybe it is the right one. I will try to take a pic today and post it if I can figure out how to.

Here's the one I got with my car.

Hi Richard:

hard to tell from that picture. Looks like the drain plug hole is on the bottom in the middle. Pretty sure it should be on the side. Look at the picture Denis posted on this thread to compare.

Drain plug is definitely on the side. The one my friend has from a 67 Z also has the drain plug on the side. Yours looks (and understand I am going from memory here - and when I say memory I mean I looked at it 30 plus years ago) a Corvette drain pan from around 1966.

Also, you have mail.
