Been posting in 4rock my bad so will repost here
Story is i bought the 87 with multiple multiple problems so I bought the 91 for parts in the process of trying to combine the 2 as far as the 88 I'm doing a master rebuild

 

Pulled the head off the 91 "parts truck" and one of the bearings is shot but the block is in great shape, clean with a small ring grove, plan to see what the block looks like in the 88 to see which one i will use for the rebuild busy at work so will be a slow one

 

As far as the 87 my front end needs much work so thinking i will take my chances on the front end in the 91 and replace the 87 front end with the 91 last Dec i put the 91 rear end in the 87 so it would make since so that when in 4wd the rear will be on the same page as the front

 

Updating my progress, it has been good week for the 88

 

Got the head off of the 88, the previous owner had the motor rebuilt, long story short the mechanic who did it did not do a good job they have about 250 miles on it since it was rebuilt then it setup for 2 years, so when i took the heads off the head gasket was folded back in the back left hand corner if you're looking from the front so that explains the water in the oil and oil in water it has standard bore on the block with no ring grove look brand new

 

Now I'm sitting here with the head take it up to the local machine shop he calls the next morning tells me I need to replace all the velvess in the head and get a headset kit, so I did and the finished product is

 

Got a little excited about all this stuff going on purchased new plugs wires so I got a busy day today i plan on fixing this thing up and driving her longer than a mile for the first time since I've had it I'm excited to see how this turns out wish me luck will let you know by tomorrow afternoon thanks
