Hey guy i need a little help. i am doing 13b swap into a 90 b2200 truck like a few other have done. I am going to run a Weber 48 IDA carb setup. i am wondering what ignition setup i have to run. i have most of the parts from a 87 gsl. do i need to run the distributor from a 12a or can i make the setup from the 13b work. If i run the 13b ignition, do i have to run the wiring harness and computer? some insight from knowledgeable people would make my work go allot faster. Thanks

Best route is to go with the 12A distributor with the J109 Ignitors. Otherwise you will have to run the computer.

If i were to run the 12a distributor, don't i have to run the twin coil set up? since i don't have any of the 12a ingition stuf, do i have to get something like a MSD box?
