I can hear and feel that its missing a cylinder. I just cant figure out why. Ill admit im still by all means a mechinac in training, this just now has to be my daily driver and ive ran out of ideas. But now i can atleast see which ones missing. Ive read several places that timing should be 12 degrees BTDC. Mine is currently roughly 10 degrees is that enough to be throwing it this far off? It will run wth the distributor centered but do to the miss will occasionally try to de at lights and stop signs but if i turn the distributor almost all the way to the right it raises the idle so it doesnt try to die but makes the truck shake quite a bit.

Ill have to check that and figure out which cylinder isnt hitting. And no i havent ran a compresion test yet i needa go pick up the guage for it.

Hello i have a 73 620 pickup with a 76 l20b. When i got the truck the head was cracked. Took me about a year to find a head for it. I finally find one its a w58 l20 round head. Spend a good fifteen hours cleaning everything up takin my time putting it all together. Finally get it timed im running the cam in the number 2 postion. Truck will fire instantly everytime you turn the key but will only hit 3 cylinders. Ive checked my valve clearance warm and cold. Ive checked my firing order even bought new plugs thinking one may have fouled and still nothing. Im at my wits end. Willing to try anything just have ran out of ideas. Any help tips or advice would be greatly appericated.
