Re: New guy with a old truck and motor
It's running hot because the timing chain was slack which made your cam timing very retarded. Those little pieces look to be part of the original nylon timing set. If I were to pop off a timing cover and see missing teeth, the oil pan would come off without hesitation. That means whoever put on the current set did crappy work and if anything else was done to the engine, it probably wasn't done properly either.
Also looks like they didn't put thread lock on the cam retainer bolts because there's no way that fuel eccentric should be rubbing on your cover. That or they didn't get the cam gear all the way on.
Given that this engine has worn out two timing chains and obviously never had the oil pan off, I can say without a doubt that the bearings are shot and that's why you have low oil pressure. Oil pump could be pretty worn too. To wear out two timing chains this engine has likely 175k-200k on it at least.
No question it really needs a complete rebuild. Could it make it to Killeen with just the new timing set?... Probably, but run it with Valvoline 20/50 oil or 10/40 with a quart of Lucas. 20/50 is what I use here in the summer anyway. Once you get it here, a complete rebuild is a must or more problems will continue to pop up.
Don't let that dissuade you though. What some guys consider to be a "budget rebuild" entails exotic parts and $3,500. And those engines are less realistic as street engines. What I'm describing is a realistic engine that's basically stock, with only the essential upgrades (cam, intake, exhaust). This will make the engine much more powerful than stock and with better mileage. But isn't a 400 horsepower monster that makes a lowsy driver and sucks fuel. It is realistic budget-wise, street-wise, and skill-wise for most backyard wrench turners and will still have more power than most folks really want/need.
To me a quality budget rebuild including the machining and stock rebuild heads should be under $1,200. And that is with good Federal-Mogul and Comp parts not cheapy rebuilder junk. The only thing I don't do myself is the machining and that rarely costs me over $250 (sonic/magnaflux, bore/hone, deck, align bore), about $300 for a Federal-Mogul rebuild kit, $200 for a mild Comp cam/lifter kit, and about $350 for the heads rebuilt (I usually do this myself spending about $150-$175 on parts.)
This way, since you spent a little extra on the cam already, you can buy the carb/intake/headers as you can afford them without having to get back into the engine.
