glad you got it running
Glad it's coming along. Do you have an EGR valve on that engine? If so, try disconnecting the vacuum to it and testing for the misfire. If you added larger pistons, valves, header your vacuum will likely increase and could be causing the EGR valve to open too soon. I had to put a restrictor in mine for it to run right
Now this is more like it!
Hey emsvitil,The vibration... Well, before I parked the truck in 2013, the tires were fresh and balanced well. I cleaned and relubed the U-joints and spline and was careful with re-installing them, so I'd be surprised if they are loose. The amount of vibration feels like tires, but could be in drive line. I will check it out, and then have Discount Tire look at the tires... geezzz I would hate to have to buy brand new tires again!... but I should have blocked up the truck.The clank at start and back up... that sounds like very sharp metallic clank with a very slight lag. I will check motor mounts and drive line. I may have to put it up on jack stands and get under the truck with my wife doing the shifting test?The misfire... it has a very slight misfire during low RPM between off idle and 25 MPH, just driving slowly in 1st gear. I don't think its spark or ignition timing. It could be air/fuel mixture? I will pull the plugs this afternoon. I will do some diags on the ignitor and coil. Yes, the issue could be 3 other bad injector connectors!.. or some wires in the harness that are not getting a solid connection or ground.I am still wondering about this cam profile. IF, after about 200 miles, and all my normal "tweaking" and verifying all systems are performing normal, it doesn't smooth out, I may consider swapping in a different camshaft. I can re-install the stock cam that was in the old head as a test.I don't have the pleasure of previously breaking in a rebuilt 22RE so I don't have anything to compare to. I realize at only 45 or so miles on a break in its still "stiff". I have read that the ECU "learns", but I would like to understand what EXACTLY does that mean. The ECU and input from the sensors have electrical ranges and limitations - what are those limitations?This rebuild has been a real challenge and interesting. I sincerely appreciate all the input, great advice, shared knowledge, and the poking fun at me. My truck is my second "hobby" right now, and it would not be as fun if it weren't for all of you who contribute to my experience!! Thank you with HUGE-ness!Gnarls.
Note:For as long as I can remember I've had an occasional 'ting' in the driveline somewhere. Noticed when windows open (esp. rear), no radio, and changing direction of travel (F->R,R->F). Still haven't figured it out, but it hasn't hurt anything..........
Yeah they can "tink" for a long time if you keep grease in them.
The metallic sound on take off/back up is usually indicative of bad u-joints, even freshly greased worn ones will "tink"As far as a lot of the sounds go, they were likely there before, its just been 4yrs since you heard them, and now with the "new engine" you are hyper sensitive to all the noises you are hearing.Can't judge the performance until at least 500 miles have passed, by then the engine should have gone through several heat cycles, breaking everything in, until then as long as it runs smoothly, wouldn't touch it. Also won't be able to judge its true performance until you run 4.56's for the 31's, or slap on a set of 28's.

You could also air the tires down a bit and force them to flex.
Michelins are a waste of money. When I worked at the tire shop, Michelins were the worst tire. They loved to separate and blow out.
I agree with everything except this statement. "I should have completely drained the coolant from the block"Please explain why?I think You could cause more issues having the cooling system completely exposed. I could see draining the cooling system and refilling with fresh.
My BFG ATs sit for months at a time and don't flatspot.............................
So, only use them off-road.Might even smooth out the off-road driving.
... The next time you are at a Costco or tire shop that sells Michelins, grab the sidewalls, and flex them. Then push on the tread face. There is nothing to Michelins. Then compare it to another tire. Michelins are a waste of money. When I worked at the tire shop, Michelins were the worst tire. They loved to separate and blow out.
Is there a chance the plug on your cold start injector is crusty like the others?
