Won't go to the trouble of documenting the TBI setup other than what I've posted in my posts about it. All the info is very well documented for that at Bills site on Binder planet at links I posted. For the cost to benefit ratio, I thought TBI was worth the effort. I think my results show it was worth it. Can you spend more money for a more complicated setup- yeh. Will the results be worth it? In my opinion no. Deve, I do like your distributor mod. I saved my original points cam lobe to be able to go back to the Pertronics or points if desired as well. The only permanent mods were the extra screw holes in points plate and slotted the hole for wires to come out. I used points cam lobe from rusted froze up Chevy 6 from junkyard I spied while picking up TBI.
