Just picked up an 89-350 LE it's been sitting 10 years and other than that is in superb cosmetic shape. I have a couple of 5 speed 12v's and a couple of 77's with 318's ....I am not familiar with the 89 360 and will need some help with the throttle body and need to maybe undue some alterations that were made on engine . #1 they disconnected (removed a belt) on some kind of a seized pump, I think it's a smog pump?? Is that correct?I I got the crank to move a little bit before I bought it , but it's bores are now full of marvel mystery oil to which I made more mysterious....131k original miles on it and not a dent some(very little) rust through on wheel wells, It's single wheel, not a dually. Any insight is appreciated, Rafe
 
Wouldn't worry about the smog pump one bit.
89 was the first year of that TBI on a 360, 2nd year on 318s. I've spent more time and $$ fighting that system than I can begin to recount.
Since, I treat that system like an uninvited house guest
As long as it works it can stay. It starts giving me fits it goes in the trash in favor of a carb conversion. Especially as they get older and parts are less plentiful. The base motor (long block) was pretty decent.
 
Thanks all, Have lot's going on ...I have only been able to get 120 degree turn on the crankshaft so I am being patient and letting soak more and working it back and forth. It's a hard stop both ways and I am concerned (doesn't quite make sense to me) don't want to move forward on it until I get a full360 or two on it. Plus I blew a brake line on (free) Xterra .....which turned into stripping the rubber hose fitting so I'm waiting on that part and might as well make up the second line on the rear while I'm in there . I am also working on the (OLD) but grand two post lift I went back and got from the seller of the LE 350 It sat in his yard on a trailer for a few years ....he let them both go .........got to form a concrete bas for it and get it operational ASAP. Don, is (how does) the smog pump affect the throttle body system .....
