I like the lift on this cam, but duration is a little long for his needs, doesn't need a "lopy",rough idling cam,needs one with about 15" of vacum for power brakes,etc...the one in there now pulls 17" of vacum at 850 rpm, idles great and has real good off-idle acceleration....but, I'll mention it to him and see what he says, price is great........

that's the part number. i have a solid roller cam a little wilder then that and it pulls pretty good vacuum with a dual plane intake. with a single plane it pulled a little less then 8" at 1200rpm, with the dual plane it would be almost double.

He's running an aluminum dual plane manifold right now, so your cam may work, vacum wise.........
