SD 455 Registry

- Home Of SD 455 Registry -         

Welcome to the 1973 - 1974 Super Duty Trans Am and Formula Registry.
The registry is intended for all 1973 - 1974 Super Duty Trans Am/Formula models.

These cars have the 'X' in the VIN.
2V87X3(or 4)N1***** for a TA
2U87X3(or 4)N1***** for a Formula
The 'X' is for the SD engine

The idea of the registry is to publish each model year in viewable format. The format will include VIN numbers and RPO code options along with cowl tag information. The registry is a work in progress and will only be successful through participation from SD 455 enthusiasts. All personal information will remain private on the registry, or at your option you need not disclose any personal information. As a fellow owner and SD 455 enthusiast, I look forward to seeing how many of these "Super Duty" models were built.

Use the link to the left for the SD 455 Registry Submission Form.

I would also like the data from the cowl tag.
You are also invited to send me copies of window stickers, invoices, build sheets, pictures authoritative literature, etc.
Any additional information you have on the SD
( personal anecdotes, first hand experiences, suppliers for rare, hard-to-find parts, etc.) would be appreciated.

STOP !!!

Have you been dinged at a judged show or think your starter has an incorrect date code?

Don't get rid of or look for another starter for your 1973 SD Bird until you read this thread!

SD Starters

njsteve on Performance Years bulletin board discovered an anomoly on the date codes for the 1973 SD starters.

It appears that Pontiac may have used starters with a date code of 1B11 which means Feb. 11, 1971!
There are at least 7 documented Birds with starters with that date code on them.

NEW! Orphaned SD Engines List

I added a page for the SD engine unit numbers.
