MSD E-curve Distributor Set Up???

Thanks everyone for their help so far. I'm going to show this thread to my builder and see what he thinks.

I'm not sure what you mean by complicated.

I mean the instructions aren't very clear. I'm still pretty confused even after everyone's posts above.

Summit has:

-MSD 8833 Billet "ready to run" SB Chrysler Distributor with vacuum adv. w/o rev limiter and no ignition box needed for $360

-MSD 8504 Billet "E-curve" SB Chrysler Distributor with vaccum adv., with rev limiter, and no ignition box needed for $380

I felt the E-Curve was the best value.

EXACTLY. I needed a new distributor and was going to run the MSD 8833. For $20 more I got the built in rev limiter and all of the programmable advance curves. Now, I just have to figure them out...
