I guess you can do that if you pick up the cam signal from a cam that still has the provision on the rear of the cam . I notice some cams are ground GEN III/ GEN. IV . Those type of cams would allow you do that .... correct ? Lots of cool “different” stuff to learn with these LS engines . You have to literally forget that old school SBC/BBC stuff and put it on a shelf . The hardest thing for me so far ... is the accessory drives and different combinations that are available for swaps . The aftermarket is exploding with this ls stuff ! When I first started this build I thought .. how much better can this stuff be than the GEN 1 sbc/bbc stuff . I changed my mind real quickly when I tore down this LQ9 . Like night and day . The engineers at GM really did their homework on this LS stuff . They must of done something right . The Mustang Ford guys are yanking out the Ford engines and dropping in LS stuff ! check out the “Knuckle Heads”(The Sloppy Mechanic) that are bolting on turbos to junkyard ls engines and making 1000 hp+ . Lol unreal !
