Cam casting #3728284

Does anyone have some way of determining what this cam is? It is some kind of small block Chevy cam.

 

Here is what I found:

"Chevrolet Replacement Camshaft
Effective as of June 3, 1965, Chevrolet substituted a physically different camshaft (Pt. #3862798, Cast #799) for the camshaft which has proven to be the best cam for the 265 cu. in. engine, namely Pt. #3728779, Cast #3728284.
Specifications are, max. lift at the valve (zero clearance), 0.3987; inlet and exhaust are open for 3000 including ramps, 2500 excluding ramps; timing degrees (from beginning of ramp), intake open 32.50 BTC, close 87.50 ABC; exhaust opens 74.50 BBC, close 45.50 ATC. The ramp has a 200 length from beginning to end on the valve opening side of the lobe and a 300 length from beginning to end on the closing side of the lobe.
This camshaft is a legal option for the 265 cu. in. Chevrolet engine. Sufficient information is not available to deternune if this is a better camshaft. Chevrolet claims the performance is the same."

Hope this helps...Tom

 

Thanks, Tom that was more info than I could have hoped for! I suspected that it was a fairly early cam because of the "372".
