Probably a old TRW/Speed Pro grind. Would need a old catalog, for specs.
 
It's a link with the TP216 cam specs. Looks like it's a solid roller for a big block.
 
Yepp its roller for big block never used just wanted to find specs lol

There are two ways to list the lift of a cam. Lobe lift and Valve lift (gross lift).

The lobe lift is how much lift the lobe of the cam has. Take that and multiply it by your rocker arm ratio to get the valve lift.

So in this case, you take the .4167" and multiply it by the stock rocker arm ratio of 1.5:

.4167 * 1.5 = .62505" or .625" lift at the valve.

If you used a 1.7 rocker arm ratio it would be:

.4167 * 1.7 = .708"
