If the computer , a silver box about the size of a half cigar box, isn’t in the battery compartment, you’d spend too much time making it work.if you’re confident in your skills, probably worth rebuilding the carb before going further. If not, there is a gentleman named Lars on the forum that rebuilds q-jets. His work is exemplary and his reputation impeccable.

I learned a thing!
Turns out the computer has NOTHING to do with the torque converter.
Vacuum controls the TC via an electric control on the firewall.
AND... It appears to be working fine.

Distributor advance is controlled by the ecm also. https://www.ebay.com/itm/Chevy-SBC-B...item2cda0d6a7b. Main dif between this and 400 buck DUI unit is 350 bucks.
THAT woke it up!
Fired instantly, idles like a different car.
MUCH smoother and actually responsive.
The old distributor must have been killing it.
One thing...
The tach is a little crazy now. bounces around some
Thoughts?
