ok, i just blew up the the 305 TBI in my truck and bought a 350 4bolt out of an 84 sub that had been rolled. i have kept all the TBI wiring in tact, and will be running my starter and alt off the it. now comes my question... can i run the hei off of the battery directly, or do i need to hook it up to a spark controller? i have heard that both will work, but want to ask the guru's for their advice. please understand before suggesting the $400 MSD systems that the wife has put me on a tight budget (sucks when they have a say) thank you for your help and i will let you know how things go.
