Comp cams XE HL 275. Anyone use one of these? How does it behave at idle? What vacuum does it pull? In Duster, 340, 9.0 , air gap, 1 3/4 hookers, auto, 10" TCI, ported J heads(254 cfm), 3310 w/pro-form main body, manual steering & brakes, 3.91. Mostly street driven now. Old cam was MP 284/484, with Holly strip dom. Good cam, didnt have enough compression for it. 3000 up it was great..only 4" of vacuum at 1000 in drive. Changing over to air gap and maybe XE HL 275...this should be an improvement the on street. Any thoughts ? Anyone use this combo? Please advise and thanks. Terry B.
