My cam was rated for 2800 to 6500 and it seems pretty accurate even with a 408. With the right cam and other parts even stock out of the box Edelbrock heads can make good power. I made 485 hp and 511 ft/lbs tq with ootb untouched Edelbrock heads (I wish they were Victor lol). Cam is a Howard's 711351-08. Has 244/248 @ 050. 108 LSA, .578 lift and I'm using Comp Cams roller rockers 1.5. 10.1 comp ratio. Peak HP at 5700 rpm if I remember correctly. We only went to 6200 rpm on the dyno but it had only dropped 20 hp off peak at 6200 so it seemed to be going pretty strong still.
