Can any body help identify cam?

[65 Cuda/ 66 Dart]

I have a 65 Cuda with a 360 that is supposed to be from a 74 Duster. The guy I got it from got it from an estate and had very limited info. on it. Externally it has an Edlebrock intake, Holley carb and hooker headers. It sounded like it may have an aftermarket cam. I pulled the engine and trans. to clean re-gasket and paint the engine and compartment. I pulled the timing chain cover and then pulled the timing chain and gears and the front cam journal is stamped with a U. Does anybody know of any manufacturers that use that designation? The vave springs are definately aftermarket and the rockers are stamped HR3ST and HR4ST. Any help would be greatly appreciated. :banghead:

Sorry, but no. You could check the cam lobes (measure the fat end and subtract the skinny side and then multiply times 1.5 for one intake lobe and one exhaust lobe), then Google the specs and see who makes that size lift.
