Cam choice for low compression motorhome 440

I'm in search of a cam for a similar car ('67 Coronet daily driver,'74 440 smogger,727,2.94's,stock manifolds).The guy at Hughes recommended the SEH2428BL,the guy at Comp suggested their Extreme energy 21-222-4. The Hughes Whiplash cam sounds like it would also be a good choice but the xtra choppy idle is a dealbreaker for me.
