Did you have the distributor advance curve tailored to the truck, gearing etc?
Sounds like its a bit slow to bring in the advance....
Misfire under load could also be a plug lead arcing across to a ground...maybe to a header pipe....in Park try looking under the hood in the dark and blipping the throttle....darkness makes the spark more visible...
I would be looking more at the distributor first...including the module...

Thanks for the comments and I appreciate your response. I can’t say enough about the forum and how it’s allowed me to silently research but this has gone too far. The distributor was calibrated to 24 degrees at 3000 RPM per the build specs and for street applications. I set full timing at 36 not accounting for this spec. Do I need to offset the timing for this spec or is 36 degrees 36 degrees regardless. It does idle on or “diesel” sometimes too.
