Final pic for the rebuild. Installed, test driven, and passed CA smog. Now I can get some license plates.
During the first test drive, it was really underpowered and ran with a lot of 'hesitation'. I figured the timing was off, when I did the timing adjustment for the initial drive, I did it quickly with the jumper in the diag port, but the idle was high. Turns out it was retarded by 25 degrees, so it ran pretty poorly. Went through the FSM procedure a couple of times and got it set properly and it drives great. Decent power, really smooth, you can't feel it running at all, barely can feel it idling if you put your hand on it. All the balancing and injector stuff payed off.
What went into this?
Machine shop $1200 (approx):
Full A/C overhaul with new Denso compressor, expansion valve, dryer, o-rings, etc...
Flush/test all cooling system components
Photoman 150 amp alternator bracket
New Denso 150 amp alternator
New gates power steering hoses
New trans cooler hoses
It's been a long process and I easily put 200 hours into the job. It is a rewarding payoff to climb to the top of the first mountain on a motor with 100 miles on it though.
Drove up to the top of Black mountain in Ramona from Pamo valley. Just 10 miles from the house.
I can see what the big deal is with these things. Drives up a mountain side like it isn't there. The off road handling is by far the best I've driven. Even washboard is handled with ease, and the truck doesn't sound like it's falling apart going over it. I'm sure it will only get better as I freshen the rest of the running gear!

Great Job- I wish I had the knowledge to do what you've done. Big Kudos to you-nice job!
Just for curiosity's sake- What engine temps are you running? Just curious how a freshly rebuilt engine compares with say, 188K engine...

Beautiful work sbman!!!
I think you're missing a ground wire at the back right of the head that goes to the firewall at a bolt that holds the wiring harness.
Here's a before pic of mine:

So far I am seeing 190 to 200 water temp per the obd reader. Usually engines run a bit warm during break in until things have seated there is some extra friction as the rings seat in.
I did notice the under hood temps really climb at low speeds and my fan does not seem to do much about it.
The floors get pretty warm and there is a good leak around the steering shaft I am going to have to fix.

Cool...thanks! Maybe a fan clutch rebuild is in order as well?
Electric fans as a wild guess....

I am planning to do an electric fan setup. I want to gather some data with the stock setup first so I can compare the difference. A lot of people seem to distrust electric accessories, but done correctly they can easily outlast a mechanical system. An electric fan can deliver good performance at low RPMs and at idle and can be optimized to work best when you need it most, but a mechanically driven fan has to make a lot of compromises.

Great job, and thanks for keeping us posted on your progress and end product. Enjoy!
My only concern with the electric fans is how they react in deep water crossings.
Should one build in an override switch to protect them? In other words switch them off for river crossings.

I will watch this thread. What is the idea though?
Looks great and nice job!
I picked up a clean non-running 97 last week and if it needs a rebuild I may have to ask you ton of questions.

Did you get your machining done in the North County?..if so where and do you recommend them?
