hello all, i just got an 89 notch that used to be a 4 banger. the 2nd owner(i am the 4th now i think), set everything up on the bad boy for drag and i was told they ran a chevy motor in it . they said it used to run 9's. i don't know though. anyway what kind of ignition did the 4's have on them. i am guessing tfi but i know nothing of these motors. the reason i wanna know is because i am doing an HEI conversion and i need to know if the tfi equipped cars had ballast resisters on the ignition. i don't think they did though.
