Does anyone know how many Julian Date Codes Oldsmobile manufactured for their F Code heads and also the dates. Depending who I've talked to I'm told only two,while others tell me six!! I know this is a tough one so I'm asking the experts. Thank you as usual.

 

My database says

"HEAD, Cylinder head, 70 "F" Casting
1970 W30 only
Known Dates 106, 211, 295, 336"

There may be more dates, but that is all I have heard of so far and/or been able to get into the info file.

 

Chris add 51 to your database. I've got a 336 & 51 that supposedly came off the same engine back in the early 1980's. Its buried under the workbench, but I'll try to get some photos of it to share. John

P.S. yes I'm a parts hoarder, but I know of a 1970 W30 project car that I've been talking with the owner on for over a decade. Someday... he just may let it go and I've been collecting parts when I come across them with that hope.

 

Your as bad as I am. I have chased some cars for 15 years before they worked out. I only have one car left I am chasing. I found it nearly 20 years ago and still sitting in the exact same spot.

 

Here's a picture of the 438 casting and the date of 51.

Somebody has to save them!

Yes, sometimes persistence pays off and we've just got to hope that they will turn loose of it someday.

 

Chris, just to further verify that date, I have an engine with a 336 and a 51.

 

Added to database.
Is there a thing on the internet where I could leave the database so others can get a copy? I do not want to get into e-mailing dozens of times. This is assuming anyone would find it useful.

 

Cool! That confirms the 336 & 51 together would be possible from the factory.

 

Chris, I don't know what would be the best way to make it available. But I have shared your spreadsheet with pulleys and water pump numbers with several people. I think folks would be interested in your database!

John

 

Great info guys.
