The BB or dot timing can be several degrees off but it will still run so as long as you are in the ballpark which is good enough for now.
It sounds like timing to me. Two things to think about. Mentally retrace your steps of what you did after the truck was last running.
Timing cover seal (speedy-sleeve) and distributor. Would you provide more detail (elaborate)?
*) Heaven forbid that the camshaft gear was damaged when the seal was replaced.
*) Is is possible for the distributor to be 180 degrees out of position IF you removed the bolt and clamp and lifted the distributor up.
I'm expecting Hotrod Lincoln to step in next and tell you how to check timing by watching the rocker arm movement. He can explain better that I.
