BTW, IIRC, this method of dating is called Julian dating.

No?

Julian date is starting at 1 for Jan 1 and ending at 365 for Dec 31,
(non-leap year)

60 would be March 1, 91 would be April 1, etc.

Here's what I use for Julian dating (just have to remember to add a day after Feb. 28th in a leap year).

And, Delco-Remy did not use the letter I on electrical parts so it would not be confused with the number 1. Also, Sept. 1966, Pontiac did not use the letter I in its cast parts (I believe that was the only year too).

I just posted in the wanted section, looking for a set of steel valve covers, valley pan and oil pan for Sister's '72 455HO YE that Jim Robertson is resurrecting.

Can anyone provide information on what years/applications the oil pan and valley pan works on this engine? I think there were some subtle changes to the oil pan on certain years?

Also, if anyone has some nice parts available that'll fit this application I'd appreciate it.

Does Inline Tube make a reprodution oil pan? Anyone have any experience with it?

Greg - below are a couple pictures showing an original oil pan alongside an Ames baffled oil pan repop. The biggest difference is in the oil drain area. It was a nice pan.

You definately want to go with a "baffled" pan.....I think ALL pontiac V8's got them after 75.

Pre-74 valve covers are needed....75 and newer had spotwelded drip rails which will not clear your bolt on baffles...

Thanks for the refresher, John. I must be getting rusty (rustier?) in my old age.

I resemble that remark!

Going from memory, the first baffled 2nd Gen T/A oilpans came out in '73. The '73 model pan has the small center hole & two slots like the right hand one in Bob's pic. believe that style rear seal was also used in '74.

A Pontiac engine builder I supplied 400 cores to for many years never liked that rear seal arrangement, he preferred the later pan with multiple slots (non baffled or the baffled oil pan) or the '72 & earlier oilpans with no slots. A '72 oil pan is same as '70-72 & in a '72 HO engine will run the 455 version of the short windage tray.

I have oil pans from 70 and 71 40's and 455's. Think they were all the same.. valve covers are difficult to find in good shape. I bought a pair on ebay last week that came in and were perfect,suprised me how good they were.guy said he removed from an HO engine. paid $100,which was a bit high,but for non dented/rusted originals couldn't pass up.. not sure if 72 changed but think it was same as 71's?? someone can confirm this who better understands 72 model year

['ol Pinion head]

The '72's are same as '71's. When I had the 400 core program going, I usually pitched the later '70's valve covers with spotwelded drippers. Now if they were W72 flashchomes, I kept them

Great information here. Thanks. And thanks for the pics Bentwheelbob. Very nice comparison.

Bill, are any of your undented oil pans for sale?

Here's a picture of the inline tube pan. Looks like it may be the same part as Ames. Has the same oil drain detail and indicates the baffle is part of the pan.

[bossbirdta]

something new. this time it's a 72....it'll be interesting to see what this one does....the pre-heater shroud looks a bit strange?????

I like it...........ALL the important stuff appears to be there....other than the clutch pedal.

You can't tell where the primer ends and surface rust starts.....

Love the picture in the barn with CRAP piled on it........it reminds me of MY barn......

[necdb3]

Looks very pretty solid. a lot of surface rust but like you said all the important stuff looks to be there.

[1971455HO]

I don't know '72's very well, heck I can't even say I know 71's that well. I only had to ask about 600 questions here.

I was wondering about the double alternater pulley???

The AC compressor & brackets are gone , that'll cost ya. Not the end of the world, but pricy. Maybe the guy has them in a box.

I would want to see more.

Yes the 3 that I have are all non dented. They are good usable pieces.I need to keep one for my 71 HO, but will be more than happy to sellyou one. Send me a PM and we can work something that is fair.

and my are 70/71 units, the drain hole doesn't look like the picture you posted. they look like bob's beat up one. plus I have the original oil fill bolts ..
