Last night was a disaster!
So it was running rough but was still drivable. I took it to my dad's and changed the dist cap and rotor. Once that was done it was missing horribly and could barely run. we trouble shooted the firing order even making adjustments to the dist and timing. NOTHING!
After 3 hours we gave up and I decided to take it to a local mechanic who has experience with these...
I know it is going to be some stupid little thing but after working 60 hours a week and coming home to the wife and 2 little girls I just don't have the energy to fight with it every night.
The only thing we haven't checked is the compression (I doubt there is an issue there but who the F knows at this point.) mainly because we didn't have a tester...

good copy. i know what you mean. i have been chasin a stumbling off the line for several months with my old dodge and just got sick of taking all my free time with that. i took it to a hot rod guy and he found the problem after a bit. timing chain stretched not enough to jump but the crank was spinning 15 degrees before the cam moved and with throttle it moved around like a politician at election time, couldn't make up it's mind...
it'll be something with electrical, my guess. let us know what it was, would like to keep that in the mental notes. best of good fortune to you.

SOLVED!
Alright so apparently when I cleaned the engine this threw off the timing. Which doesn't make a whole lot of sense but whatever. When I replaced the dist cap and rotor I used the firing order that I thought I should 1-5-4-2-6-3-7-8. Apparently when the engine was rebuild they used the cam out of the 351 or it is an HO, which I now think it is, and should have used 1-3-7-2-6-5-4-8. 
As you can imagine it ran like total donkey *****.
And since we thought it was right no wonder we couldn't figure it out.
Anyway. The guy fixed it up corrected the timing and only charged $40!
Which I would have paid in the beginning of this whole mess. Really nice guy to, which is always a plus.
I need to learn how to adjust the timing using a light...
Thanks for all the help! I had to take a little ribbing from the Napa guys (my father in law owns the store and recommended the mechanic) but boy was it worth it to not have to worry and fight with it while getting to learn something new!

They changed the firing order for the 302 sometime in the 90's (1995?) to 1-3-7-2-6-5-4-8.
So what you say makes total sence. Shows the engines been worked on in the past.
I would not have guessed that in a million years either. Kudos to the mechanic.
