I was talking to a fellow moparts member regarding my LA-built (no broadcast sheet) 1970 cuda and the question of axle ratios came up. I bought the car years ago out of a side yard in Sacramento. It retains all of its original paint/interior but when I bought it it was missing the hood, engine, trans (had 23 spline and a scatter shield), rear axle (had 8 3/4), and fender tag. The title, dash VIN, and all body VINs match (BS23VOE128882). By looking at the car I know it originally had:
-440-6bbl
-FK5 paint
-black vinyl interior
-shaker hood (hole in firewall)
-std gauges
-non-console 4spd
-manual steering
-longitudinal body moldings (with pin stripe around it)
-body color mirrors
-AM radio
-standard cuda stuff (hood pins, moldings, dual exhaust, etc)

My question is: is there any way to tell whether it was a track pack or super track pack car? I've heard rumors that there is, but nothing more than rumors. In any case, it will receive 4.10 gears because...well...all of my cars get them.

Also, does anyone on the West Coast (car is in WA) inspects/documents cars?

Thanks in advance!

Well if it doesn't have disc brakes then it for sure had 354 gears. The tough ones are the cars that DID have disc brakes, those could be either 410s or 354s. Then there's no way of knowing other than the speedo gear.

Sorry, forgot to add that it had power disc brakes that are still on the car. But as I said, no transmission so no speedo gear..

No accurate way to tell but I would be leaning toward the super track pack because a person possibly switched in the 8.75 because that is easier than a gear swap in a Dana ...

Did you check with Barry Washington to see if he has anything ?

Thanks John; I'll ask Barry.

I have not heard of anything for it.

Didn't Super track pak cars get 26" radiators (aka maximum cooling) vs 22"?
