318 upgrades

I have three boxes, a chrome box that was in the truck with the 318, a orange box of unknown condition, and currently in the car with the slant is a box that is sort of a goldish color. I'll probably get it running with the box thats in the car just becuase i know it works then play around with the other two

I've heard that you can do a lot with the stock box so thats the plan, use it for what I can then if i need to upgrade later i will.
