Hi there. Okay, I found the engine. Hoping to go with the local one from the 98. Agree with LesMyer that it should swap in just fine. I think it makes a LOT of sense to put new plugs in before the engine goes in the car. This should all take place before March .
So, I am looking on getting the ACDelco 41-993 plug x 6 and putting them in, as is, no grease, I've gotten in the habit of just threading them in as they come and never have had a problem. Probably will use my 1/2" drive socket to get old plugs on new engine out, then it is just a simple matter of putting them in while the engine is on the pallet or ground before it gets lined up, bolted up, oil in, connected, hooked up etc before the "moment of truth."
That, and a new ACDelco 9746T wire set.
Should I even go for a new distributor cap and rotor, but will the guy be looking at me like "OK that's extra" if I show up wanting to do "that too" before engine goes in? This is my "forever truck," yeah, but I also want to not make myself have a HUGE bill on the labor. The engine costs 650 so that's good.. free delivery.. should work fine, that yard is known for more quality parts....

I’m about to drop some new double-plat plugs (ACDelco) into my 98 LT. I’ve seen several articles and threads in the recent past, that were telling drivers to disconnect the steering knuckle to access the two rear plugs on the drivers side. In contrast however, I saw several other folks stating that the steering thing is unnecessary, and recommend that you just cut the wheels to the left or right side respectively...
Which way is the most intelligent method?

In all honesty, I'm not sure it has to do with logic. But to me, pulling the steering column is easier then trying to fish a socket in and out of behind it. And it being only the #3 plug, other 2 are fine.
it's really not to difficult to do, and after doing it once, it makes it easier to do the next time, and so on...
