What can I do that's cheap?

I just looked over a old hot rod article about this and was curious if I could use the springs out of a msd distributor to put in my mopar distributor? We have a few old msd units sitting around from my dad's mustang so that would make it very simple.

Also right now I have my initial timing set at 15 and my advanced is 34. With the lighter springs will it want more advanced timing in theory?

You need to be able to limit total timing somehow. This is where the Mallory distributor comes in. You will want somewhere around 20 initial and 34-36 total. My Ford truck, for example. It has a 351M engine. They have notoriously low compression. I have it at 24 initial and 34 total. It's actually very snappy for a 351M. They are usually dogs.
