No problem Howard.

Just know that all of my work WRT equipment codes has been (and will continue to be) laid out in tabular format, rather than a list. (I also try to make it a point to "sign" my work.) My intent was not merely to repeat the Trade Letter info, but present it in a way that made it easier to distinguish availability between models. (I hope I achieved that.)

Know, also, that I have charts roughed in for 1951 (24th Series) and 1953 (26th Series), but won't be able to finish them for public release until I can lay my eyes any of the relevant Trade Letters (or bona fide copies thereof).

Now, based on what I can tell from the parts book (and it's complicated), the 327 engine became standard installation in the 2611/5401 Clipper Deluxe and the 5411 Clipper Super models. However, applications for both standard and hydraulic tappets are shown for these models - as well as those with the 288 engine. "Suffix H" is also noted for hydraulic tappets in the 288 and 327 engines in these models.

Yet, I found no option/code for hydraulic tappets in the ONE Trade Letter I've seen for 1954 models. Again, there were likely other Trade Letters issued, but until we have them, we may not be able to see the full picture.

Perhaps it wasn't a buyer's choice, at least in 53-54.

Meanwhile, Ross' correlation of hydraulic lifters with Ultramatic equipment sure seems to fit.
