Before I bought one, I'd go through the wiring one more time. Heavy red has power all the time? Heavy black to good ground? Small red has power with key on? Small black to coil negative? Small orange to coil positive?

If all of that is good, grounding the white wire should produce spark like described above at the coil wire. Coil wire needs to be connected to the coil. Other end metal terminal 1/2" from ground. Every time you ground the white wire, it should produce a spark.

Even then I would still try to borrow an OEM coil because your msd coil could be good. Wont know until the 6al is tested with a known good coil.
I have the coil wire on the coil and the other of the spark plugs 1/4 away from a ground and I'm tapping the white wire still nothing

Shouldn't be any spark plugs involved in this test. Just the other end of the coil wire 1/2" from ground and by other end I mean the metal part that snaps on the distributor cap.

Do the same test with a known good coil. Factory stock coil is the most reliable if you know someone that has one laying around. Doesn't have to be anything special.

Ok. That's just the rev limiter verification. if you have done all the tests correctly and the coil you borrowed is good, this means the 6al is bad.

Curious, where are you?

So can I ask does the 6almsd box need tack signal

It doesn't need tach signal to operate. You can completely disconnect the tach signal (gray wire) and it would work provided its wired correctly. New doesn't always mean good but I would be surprised if it was bad out of the box.
