    ...1988 350.. were those tbi and computered? was thinking it shouldn't be, but i haven't dealt with that year model truck really.

    if that were the case then i could see it being the issue as well. hopefully someone will chime in on it also soon.

    They had OBD-I systems, which could still be finicky with a big cam.

    Is this your first cam install? (just out of curiosity) and what brand cam is it? Did it come with the timing gear pre-installed?

    Did you remember to disconnect the timing wire when you checked it? That would cause the line to jump when you put a light on it.
    On that one it should be in the relay box on the firewall. It's a tan wire with a black stripe.
