Timing issues
Off to work friday and the truck starts acting up, loosing power and what not.
then dies as I pull off into work, crank on it, no fire. second attempt she fires up like it flooded.
I cleared the flood, and drove into work with out further problems.
End of day, no start...
fuel air spark, all good.
So I rotate over compression stroke, #1 top of cylinder, dampner at TDC...
Pulled the dizzy, checked the roll pins on the gear... all good.
throw everything back together, and she wont start or run unless shes at 30 to 40 degrees of initial timing!!!
She starts, runs, and drives like normal but way too much timing

Chain
Unfortunately the first thought in my head is that the timing chain has jumped...... just too many things happening at once for it to be a simple timing problem.... although plugging in an old ignition box wouldn't be a bad test, god knows those thing can give off some bizarre symptoms when the are dying......

msd box... dont have any spairs laying around...
Timing chain was my thought too, but I just replaced the timing chain about 30,000 miles ago.
She dident pop or nothing, it was an icy day and I was puttering about 40 mph all the way to work

Someone else here had a world of trouble with an MSD distributor - it'd be the first place I look.
On the other hand, if it's been a while since you checked the timing, the damper ring might have slipped, and it just LOOKS like it's 30-40 degrees advanced. And while you were messing around with all the other stuff, you fixed a bad connection.
Pull plug #1, rotate the engine until it's at TDC on the compression stroke and see where the timing marks are. Do that first before you do anything else.
