How do you adjust the weights and springs in an HEI ignition to adjust the total advance?

Ryan,

You need to pick up a kit for recurvin that sucker. Basically, you remove cap and rotor, remove the advance springs then the weights. Install new weights (some people grind their existing weights for desired advance) and choose springs that bring in that advance by the desired rpm (usually 2800-3000 rpm). Kit will come with instructions. Cant offer any advice as to what kits you should use as I run an MSD HEI.

If your not comfortable with the recurve I would suggest finding a shop with a distributor machine and having them do it.

BTW, if the current set-up is already giving you correct amount of mechanical, say for example, 24 deg. on top of 12 deg. initial timing then all you need to do is to swap the springs to bring it in by desired rpm and leave the weights alone.

What are you currently at with mechanical?
