Determine what the specs of the oem cam are. Do you know? Has anyone here physically measured duration @ .004”, .008 etc or @ .050”, .200”, know the lobe lift, the lobe separation angle and where the intake centerline is? Can’t make recommendations without knowing the cam specs you have. You’re looking for improved low to midrange increases. I’d start researching outfits that can re-grind these cams. Endless lobe profiles exist that could possibly be ground on your core. You have options. But it’s not a pull a cam install a cam simple deal. Lots more to it than “bolt-on”
