Chasing a ghost in a 350 SBC.

With some of the aftermarket camshafts it will take alot of initial timing. There is nothing wrong with it. Check the total timing at 3500 rpms and above to make sure all the mechanical advance is in at 3000 rpms. The silver bushing allows 25 degrees advance. Check out this website for 10* and 14* advance limiter bushings it sounds like you will need them. Tuning MSD Distributors. Usually it takes one blue spring and one light silver spring to get the advance all in by 3000 rpms. Use a vacuum guage to tune your carburetor. Adjust the idle mixture screws out to get the highest vacuum reading.
