Well, worst case scenario confirmed. This thing had a bad miss on one cylinder when i was loading it up. Was hoping for just a fouled or bad plug wire.
But, no such luck. Did a compression test on it this morning, 110-120 on all cylinders, except for #8, which was 20. So I pulled the drivers side valve cover and cranked it over, the rockers are rockin' so I know the cam isn't wiped, guessing a burnt valve? Cant confirm that till I pull the head off, and then the truck isn't mobile, and i'll have to commit to doing an engine build, or swap or something.
I think I'll just leave it alone for now and weigh my options, work on body and suspension work in the mean time.
