To make a long story short, I am putting a used 350 in my truck. I want to build another engine, and I will, I just would rather focus my funds elsewhere on my truck rather than on the powerplant at the present time. I would like to get my 1 tons swapped in ASAP, get them locked, and get a winch for my truck. I've got my 38s to install too and I want to buy another set of 15x10 8 lug wheels to use them so I can have my current BFGs as well as the Swampers so I can keep them off the pavement as much as possible even though my truck doesn't see much street use anymore. Anyway, so my friend gave me this 350 that he said, "It ran fine, it just needed a carburator." I do know where it came from, a guy in town used this truck for his lawn service but it got too rough in its age so he sold it to my friend who bought it for the TH 350/NP 205 setup he had so he could put them in his '76 K20. He didn't need the engine and since I hooked him up a lot in the past, he hooked me up with it for free. So, I figure I'll slap my Performer intake and 1404 Edelbrock on it now for the time being and it'll be fine, right? Well, in the process of removing the intake tonight, I found the #1 intake pushrod sticking out of the rocker arm about 3/4 of an inch. /forums/images/graemlins/shocked.gif So, obviously the engine ran crappy due to a dead cylinder. The carb that was on it was a piece of crap anyway, just your typical 23 year old Quadrajet with a throttle shaft so worn that I imagine it wouldn't run an engine on all 8 cylinders very well. So, what do you guys think? How far does a lifter have to make its way out of the bore before it seriously affects oil pressure? For the time being, I've removed the offending rocker and pushrod. Do you guys think I should just put a used rocker and pushrod in it and put this engine in my truck, or would I be better off if I didn't bother to use this engine? I would really like to get my truck to run in the next 5 days that I have off work so I can concentrate on other things. I've put out a lot of cash at the moment so I really would rather not spend a whole lot of money right now. I'd hate to have to pull the motor out of my K30 and use that. It's pretty worn and has seen a rough life...not to mention that I want to get the axles from that thing and get rid of it ASAP to have money for the new wheels and winch. So, what do you say? New pushrod and rocker, ditch the engine, or what? What the hell could make a rocker arm wear like that? Hmm...maybe the lifter wasn't pumping oil to it. Replace the cam with an $80 Summit cam? I'm just undecided at the moment. I really just want to get my truck running and worry about everything else later. It hasn't ran since August 24, 2002 when it threw a rod due to my stupidity.
