340 max camshaft with exhaust manifolds

The 1970 Mopar Hustle catalog listed first recommended improvement were LD340, 3310/780 Holley, and Hooker underchassis headers, - no camshaft !
you realize they invented "cheater" cams for reason...P4007275. Next time your at a national event ask the stock eliminator racers there cam specs...I've yet to get a response.
