I have a 86 s15 4x4 i put a new engine in it and i am changing the tbi to carb. I have a edelbrock intake bottom and top and a 390 cfm carb. When i did this before on my el camino i have to put a vacuumed advanced distributor. I can't find any information on this. Will i need to put a vacuumed advanced on my s15 too? What else would i need to change. Also any suggestions on what kind of headers.
