Estimating Cam Specs

I acquired a fresh shortblock that I have used in my car, and would like to know if there is a way to estimate cam specs from other information. There were no markings on the end of the cam, which is a flat tappet hydraulic. It idles around 950 rpms with 15 degrees of initial timing and only pulls 8 in/hg at idle. It sounds pretty rowdy and pulls against a 2,200 stall converter to the point where I think I'm going to have to get one with more stall. Its a .030 over 454 with flattops and '68 closed chamber heads, compression is around an actual 10.1. I'm not goint to pull valve covers off a perfectly detailed engine, but wonder if there is a way to ballpark estimate specs based on this info. If I am going to replace the converter, I'd like to get it right on the next try. I was told it was around .540, aint' no way this is true based on other big blocks that I've owned. All advice appreciated.

Might contact "jakeshoe" on here. He's bigtime smart on OD transmissions. And, he's also in TX.
