Calibration Info & Part #'s

[Gary Lewis]

Perhaps this belongs in the Merry Christmas, The Documentation Is Ready thread, but I think it also deserves its own thread.

I just added 411 pages of Ford nitty gritty documentation to the site. Some of it is on the new page entitled Calibration Info & Part #'s. And some of it is on the already-existing pages for the various carbs, but you need to start on the Calibration Info page to have the code to unlock the doors on the carb pages.

The info is in pdf's extracted from the MPC and, as in the new style, can be searched, zoomed in on, etc. And the info provides the detail to tell what jets your carb came with, what power valve, what barometric pressure sensor, etc.

But, it took a fair amount of thought to create the verbiage to help you map your way through the maze, and I'm not sure I did a good job there. So I'd REALLY like your input. Can you follow it? If not, where do you get lost? What needs to be changed?

Wow! Lots of info. Works ok to me.

Looks good from what I saw, do you need me to send you the original calibration label/number from Darth?

Thanks guys.

Bill - I don't need calibration labels themselves because there's not much on them, if I understand correctly, than the number itself.

But you did send me the vacuum routing diagram: http://www.garysgaragemahal.com/460-v8.html

I believe there were only 2 different calibration codes for 1986 F250/350 with the 460. AllData didn't give the calibration numbers on those. Most of the other engines calibration numbers are on the diagrams I sent you, that should help with a lot of them.

The Application tab shows 5 for a 1986 F250/350 w/a 460:

• 2 for a manual tranny ex CA

• 2 for an auto tranny ex CA

• 1 for CA as both the manual tranny and the auto trucks got the same code

It is interesting to note that the first character of the calibration code appears to tell the year it was issued, although I don't know that for sure. But it would be calendar year, not model year, as one of the codes used in 1986 (4-98S-R11) was also used in 1985 but not in 1984. So it is as if the code was issued in late '84 for 1985 models.

And the suffix, the "RX" part, is the revision number. But, there are huge gaps in the revision #'s. For instance, as shown below, in 1985 there's a 4-98S-R0 for manual transmissioned 460's in CA, and there's a 4-98S-R11 for them, but nothing in between. However, the automatics did have a 4-98S-R10 in addition to the R0 and R10, but no R1's or R5's or.....

And that seems to leave the middle, the "98S" in these cases, to tell what the application is. In this case the 98S appears to be for California specifications. And, that tracks as 98S was used for all 460 applications in California for 1983, '84, '85, and '86.

Last, note how clear the following blowup is. This is from the pdf and is zoomed in 800%. Had I taken screen shots of the 411 pages which I posted I'd still be working on them. And, if you were then to zoom to that level the image would have been quite blurry. But, by extracting the pages as pdf's, y'all can search them, zoom them, etc to your heart's content.

The clarity may not be all that important on these pages with fairly large characters, but I have some pages from the dealer facts books that are almost impossible to use in the image format. So, now I need to go back and re-work those pages.

Thank you Gary! This is awesome. To me it seems very nicely mapped out and logically organized. I have a carb kit that I want to put in a spare YF for the ‘81 and these pages will be very helpful. I don’t know how good I will be at achieving the specifications, but hopefully it will be better than whatever generic instructions come with the kit, or just carefully putting it back the way I found it... which is what I have usually done in the past.

1985 460

Gary, the assumption that the first digit is the year of release is probably correct, if you look at the 1983 calibrations for the 460, one of them is 9-97J-R0, which would indicate it was one of the last issued in 1979 when the 460 was going to be phased out. In 1979 only trucks had 460s available.

Gary,

Thank you for putting up these pages!!! That was a lot of work, I'm sure.

I just sent my first FTE'er to them, I hope it goes well. :)

Welcome, Chris. It was quite a bit of work, but hopefully it will help people who really want to figure out what they have - or should have.

And, now I don't have to do it for them.
