283 2BBL Cam selection

[Chipper Chapman]

Can anyone shed some light on what works and what doesn't necessarily work in reference to duration and lsa in a 283 2bbl combo? Looking at the intake and carb I feel like this is something that is not going to want a lot of rpm. If that is correct I would assume a shorter lsa is required to use the available rpm range, but what range should I be looking at for in duration?

Thanks, Chris
