What Camshaft

I’m getting ready to build a 408 and am trying to identify what cam to use. The block is a 91 360LA block w/ provisions for roller lifters, so I’ll likely stick to a hydraulic roller cam. Here are the specs for the engine:

408 ci (9.7:1 SCR)
Indy X/RHS heads (flow 271 cfm @.550 int, 195 cfm @.550 exh)
1.6 rockers
Carbureted (I have a Holley 750, 850, and 950 to choose from)
Edelbrock Air gap intake
727 (9.5” dynamic converter)
3.91 gears w/ 28” tire.

The car is a ‘68 Dart street car, so I don’t need anything too crazy. What would you guys go with?
