time to rebuild

[73chevyman]

well got to the truck last weekend and was trying to figure out why it was back firing. Well what i didn't want to see was true. it was backfiring due to #4 exhuast valve not opening. I was hoping that the lifter lunched on me. got to the lifters and they were fine but the #4 lifter had a 1/4 lobe in it. so i had no choice but to pull the cam shaft out. it was scary looking lol. it was completely round. it was so round it looked like it was made that way lol. got all the parts today and tomorrow i'm going to start putting everything back together. I've done my share of research on this site and found every answer i was looking for. this will be my 3rd upper end rebuild but the the first 2 didn't go too well now i did my homework and this should go as planed. what this is boiling down to is thanks for all the info people has put up it does help people like me to understand things like valve adjustment don't want to whip another cam cause i just threw it together well time to get her to perrrrr like a 350 should
