1985 350 HEI dist. replacement

[Zach079xxx]

Went to the shop I deal with a lot today to get my timing adjusted. I ran it down the interstate last week and it heated up and let me dizzy come loose. He was out in th shop, me beside him, adjusting it. He didn't know what he was doing or something and before I know it my engine was smoking like a freight train. He burnt up my control modulator is what he called it. Stores want anywhere from 140-200 dollars new or re manufacture. He says I might as well upgrade my dizzy, and if that's the case I want MSD. He says over 100k miles it's time to upgrade it. I have NO clue what I'm looking at on summit. Whatever dizzy I buy, it has to have everything needed to run.

Can you guys shed some light on what I should buy? I don't have th funds for this being I just spent 2500 on my rebuild. Any help would be appreciated.
