Might want to see if there's any ID markings under the cam gear.

I agree 300 is the advertised duration.

You can see if it's a solid or hydraulic and if it's a flat tappet or roller (be sure to not mix flat tappet lifters up- the lifter is married to the lobe it was used on). I suspect it's going to be a flat tappet hydraulic, like 99% of the SBC cams being used today.

Measure the valve lift at the pushrod and see if that, along w/the 300 degrees advertised duration, matches up to anything.
