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. |
