422 dyno fail

I don’t see anything that really stands out as a red flag on the dyno sheet, other than the ridiculously low numbers.

That said, I’m confident that the issue with the low numbers isn’t that the “combo” is that bad.

Cam is in wrong, carb isn’t getting full throttle, timing mark on the damper is off, timing light is off, carb sucks, etc, is where I’d be looking.
Or...... the dyno is just wrong.

Even very mild stock engines will make over 1 ft/lb per ci on the dyno with headers.
This motor barely does it?
Is it “possible”? Sure...... but.....Not likely.

I’d be more inclined to retest somewhere else........ that’s known for producing good power from Mopars before I spent a bunch of $$$ on engine parts.
