SD455 Starters

[njsteve]

Just thought this would be interesting as it addresses a date issue with starters on one particular high performance application: the 1973 Super Duty 455 engines.

After we got dinged for having what was thought to be a way too early (though original) starter in my 19,000 mile SD455 Formula, I did a little research with other unrestored low mileage SD455's. (as a result, the Vintage Certification score is in the process of being recalculated)

Here is what we found out:

All of them had the exact same early dated starter built on the same exact day, more than two years prior to the car's being built!

This actually came as a shock to the SD455 fraternity out there who didn't realize this anomaly existed.

The 1973 SD455 appears to have used a particular starter, model number 1108436 and they all (so far that I have found) were manufactured on the same production date of 1B11 (Feb 11, 1971)

11,000 mile white/red Trans Am automatic: VIN 137XXX (mid-June 73 ship date)
40,000 mile green/white Trams Am automatic: VIN 139XXX (late-June 73 ship date)
10,000 mile red/white Trans Am 4-speed: VIN 141XXX (early-July 73 ship date)
19,000 mile Formula automatic: VIN 142XXX (mid-July 73 ship date)
1,700 mile red/white Trans Am automatic: VIN 144XXX (late-July 73 ship date)

So far, this time span/VIN span covers the majority of the shipping time frames of the 1973 SD455. Quite interesting indeed.

Here's some photos:

Steve, as we ( you providing the lionshare), collected data it became apparent that this anomaly became the norm. This information has benefited hobbyist, especially those focused on these rare and amazing cars.

The goal in initiating thread such as this is to gather information, gain knowledge and solve the many mysteries surround these cars which we all obsess about [img]<<GRAEMLIN_URL>>/smile.gif[/img]

Here's the link to the car's thread page with the score breakdown at the time of the MCACN judging. I'm anticipating that it wil be updated soon to reflect the starter info.

A friend just found one dated 3b63

There's one on eBay for $2,100.00! and, of course, Goat Hill has lots of them :-)

I'm looking for the correct one for my 74 SD455 if anyone has one.

Here is the brutal Solenoid (Switch) that should be on these starter motors as shown in the MPC.

Solid steel construction. No Bakelite end as on the cheaper version.

I once owned several ‘67 GTO HO cars that had this “Switch”.
