STR 530 Camshaft

Is this the spider drive 649?

Ok, has anyone run one of these for the road? My 66 (not an everyday car, not used in heavy traffic) with the N/A 1380 is looking at getting one of these just for the hell of it. I was wondering if I could pull a 3.44 FD with a 2.54 first gear or whether it would be better off sticking with the 3.7. The thing is otherwise all singing all dancing. (running an 11:1 CR), I like the idea of having a cammy car before I go back to supercharged pleasure. (10psi running a 266 style supercharger cam with more exhaust duration/lift) 264/288. I've lined myself up with a set of 1.5 su's as well.
