[quote=The Sphinx] I have a 360 with eddy out of the box heads, hughes 1.6 rockers, 10.5:1compression and a MP .557 cam, MSD digital 6 ignition with an msd pro billit distributor that is locked out, Holley hp750 with 80/82 jets, Eddy airgap intake. For some reason my car just wants more timing. At 36 it runs awful, 41 degrees its happier and I'm nervous about giving it more, but the car runs faster the more I give it. So far Ive ruled out the balancer, distributor,and ignition box as I have swapped them out with No change. I did degree the cam and everything came in spec with the cam card and left it straight up. Anybody have any input on what I should do next? [/q

Something is wrong if it runs bad with less timing if timing was retarded it would be just down on a little power not run bad. sounds like more timing is covering up a problem.
