360 will not start, any suggestions?

just because the ECU goes bad doesn't mean you have to change to an HEI setup. thats alot of wiring for nothing

simple replace the ECU box and done deal if thats the problem. I can't stand people saying mopar ignitions are junk, but truth be told most ECU boxes are 30+ years old and still running the vehicle!

GM hei is not alot of wiring, put a jumper on the ballast, unplug the factory connection at the distributor, find a junk yard distributor connector, wire it to the hei module, hook up hot and ground.
Add a simple internal resistance coil in the factory bracket.
You are running without cutting any factory wireing.
For around 50 bucks you have hot spark that any part store has parts for.
