HEY GRUMPY< Not sure which of these to go with. It's a "street stock" type circle track car. 10.5:1 compression, unported stock intake, heads, and exhaust manifolds. 3200 lb car, want power between 3500 and 6000 RPM Camel hump heads, 1.94/1.60 valves.

Id suggest this flat tappet solid lifter cam

Id bet it easily out performs either of those, the tighter LSA, slightly increased duration, will help flow in the ports and exhaust scavenging and a solid lifter design has better valve train control all make that more likely, keep in mind you need a tight LSA to allow the smaller ports and valves to flow efficiently, if your dead set on a hydraulic flat tappet Id go this route, IF its allowed I use 1.6:1 ratio rockers also

why not call
crane,1-866-388-5120
crower,1-619.661.6477
erson,1-800-641-7920
lunati 1-662-892-1500
isky 323.770.0930

and talk to the tech support guys about what they suggest but DON,T mention anything any other cam manufacturer suggests during the conversations, just present the info on the parts used in that combo, rear gear ratio, compression, etc and see what they suggest, then make up your mind.
