got another computer, this time out of a Chevy 1500 with the 4.3L so everything matches. For those interested I have a spare 122747 ecm if anyone wants it. Just needs the chips.
I got a ESC, just need to get a knock sensor. I also got a EST to change the distributor over to be computer controlled timing advance.
Im working on the tbi plate, Tapping out the holes for the 3 tbi bolts. One the first hole, the tap snapped and broke off in the hole when just about through. Ended up driving it out with a chisel and a BFH. The other hole went great, on the last hole the tap was just to warn out and didn't cut the threads deep enough.
Still need to get a fuel pump, thinking it might be better to just buy a new pump as most of the vehicles that I know have external mounted electric pumps are from the late 80s to early 90s. Within a few weeks I should have something going.
