so i have a mopar performance cam in my slant. included with the cam were several pages of install instructions/lit etc. the cam is mp 268-108. 268* duration 52* overlap .460" lift.
heres my problem. they included two valve lash specs. one says .028 intake, .032 exhaust. another one says .016 intake, .020 exhaust.
i ran the car for a while with the larger gap, but it was super ticky and grumpy and didn't make power. i reset the valves today to the closer specs, and yes the engine (when in park) runs GREAT!! lumpy, racey sounding idle, sounds ready to rock. drop it into drive, idle drops to 400 and it just wants to shut down. when it's moving it's great, but stop lights are an issue. i cranked up the idle speed screw, but that didn't really help, still wants to stall, and will just waste gas.
any one running this or similar cam? what valves specs are you at? will probably just split the difference when i readjust tomorrow.
