I know a "J" on my VIN is for the 190 hp 350, instead of the L82

This site is the mother lode of 73 info:

The VIN codes listed in your site are the 1972 codes.

In 1972 engine code CDJ was 350, auto w/ California emissions controls. The codes for 73 were different and there's no J code. Maybe yours was a late 72, titled as a 73??? I've had that with a Volvo and an MG that I've owned.

My thoughts exactly! The 68 Mustang's "hot" 302 4bbl motor is refered to as a "J" code motor. I think it was rated at 250 or 275HP. I'll take a 290HP 302 Chevy any day! I actually still have the one from my 69 Z/28 sitting on an engine stand in my garage (you "Nerds" out there, don't start getting too excited! my motor was blueprinted and the "DZ' stamping is long gone after we took the deck heigth to 9.00".)
