cool lobe is over-rated it's better to have a good running engine. Buddy took your basic combo in a 68 charger, added summit 488 cam, headers, t-chain, MP electronic ing, DP4B intake (I think) stuck w/ the Cater carb and the car ran 14.10 driving like grandma. it will work with mani's. You could also look at the mopar 528 solid, although it would like a little more gear.
