i am going to rebuild the 460 in my glastron carlson cv 23 this winter. the pump was just rebuilt by dons pump service, "a" impeller with inducer, and place diverter. new motor will have 10.6 to 1 comp. with aluminum motorsport heads. i run a bluethunder dual plane dual quad intake with edelbrock 625's, and msd ignition. i can not change the stock hardin marine logs as there is absolutely no room in the engine compartment or in the rear interior for any change there. my question is what cam to run. it has a comp cams .530 lift flat tappet hydraulic now and turns 4900 rpm @63 mph, with this tight pump. anyone with "hands on" experience i would greatly appreciate your input. comp cams and crane cams suggest 2 way different cams. so what to do? pump premium 93 octane fuel will be used . thanks to all
