I’m very happy with my cam. It is basically the same cam that's in my 434ci race engines: Solid roller, 264/272@.050, .680 lift, 106* lobe separation for street, 108* lobe separation for race.

430 inch small blocks can use a bit more cam without losing drivability, especially if the port size is kept small to maintain low rpm velocity. With small ports, mine will cruise at 2200rpm, idle at 1200rpm, and run out of breath at 7100 rpm. Where as the same cam will turn 8000rpm in my race engine with big heads. With the small-port street combination, low rpm torque is excessive, even with 13” RR slicks.

Get it carbed correctly and it wont be bad to drive on the street. This combination needs a custom calibrated carb from a good carb builder, not for power but for drivability. An off the shelf carb, whether a Holley, Demon, or whatever, usually will give up some drivability with this type of combination. Street calibrations are the hardest to get right, I think DaVinci does Craft’s and I’m very happy with my Stealths.
