Looking great!  That's a great visual on how torque arises from a long stroke.  Just 4 cylinders, nothing crazy regarding bore, but look at that tall powerplant with the long stroke.

 

Keep updating!

Yep these are long stroke motors for semi modern engines. Compared to a high revving Honda ect they are like tractor motors. With the right cam they will spin though. The cam I'm using in this will wrap right up to 5.5k redline in quick order.

 

My BIL is into old Willy's Jeeps. Those old 4 cyl have connecting rods that are about 18" long. Of course they only turn about 3,500 rpm.

I knew I couldn't be the only one with a 4WC in a Zu. Someone just turned me onto this. '90 Isuzu 4wd standard cab pickup with '84 fleet for sale in Reno. The whole rig is less than I paid for my camper.

Looks to be fairly stock and seems to carry the camper well.

I have been working on this along with a few other distractions since the last post. I've had a couple of redo's as usual. The worst was I had the entire valvetrain installed and coated with a very glue like assembly grease. I covered it up with the valve cover and decided to screw in the oil fill cap. I instantly felt a crunch, crunch and stopped. Too late! I had sandblsted a few parts and then cleaned them and cleaned them again. chasing threads with taps ect to make sure there was no sand left. I didn't get the oil cap threads clean enough. When I screwed in the cap it dumped a couple of pinches of very fine sand right on my new cam and valve train. So that ended up being a day to redo and super clean everything! Hopefully tomorrow this will be ready to drop in the engine compartment.

 

This is tonights cut and paste from the Isuzu forum.

Didn't get quite as far today as I had hoped but I have a lot done. I had hoped to be ready for the flywheel and clutch tonight but still have a couple of hours work to do before that. Mainly clean and install the throttle body.
I remembered to put some bolts in the flywheel end of the crankshaft before I put the drill on the oil pump to pre-lube the engine. Sure beats pumping oil all over the floor like I usually do! :roll:

What's that sticking out of the engine? In this engine I am using a no longer made performance mid range camshaft from Calmini. it's probably the best of what has been made for these engines over the years. The combo of cam, header, and high flow exhaust really gives a kick in the pants to these motors.
motor%20003%20Small_zpsl67m5zj1.jpg

Timing marks painted and set. red marks are #4 TDC white is #1.

Everything lined up right on the money.

Timing set on cam and dist. Engine prelubed. Valves adjusted. Calmini cam calls for .006 intake, .008 exhaust.

Header on for pretty pics. It's used and has a little rust. But I cleaned it up pretty good with a Scotch-Brite pad. The engine will go in with the stock iron manifold for now. I'll add the header and a high flow exhaust later. new plugs gapped, threads coated with Anti-Seize and installed. I need to pick up some new plug wires.

I sandblasted the rusty air tube and painted it with High temp paint. it will still burn off before long.

Now that's what I'm talking about! :D
motor%20028%20Small_zpssaskybnl.jpg

Lower intake installed.
motor%20029%20Small_zpsmfhxjbju.jpg

I had some brittle and broken fuel injector connectors. So I spliced in some good ones from an extra Trooper engine harness. The harnesses are not quite the same so I couldn't just swap the harness. All splices soldered with matching color codes connectors and heat shrink then wrapped with tape.

Done before I had to take it back apart to reroute some of the harness. I reused the fuel injectors from this motor. They had been cleaned and flow checked when my bud rebuilt this engine. I had no gas smell in the oil prior to indicate leaking injectors. Cross your fingers! All new O-rings and seals of course.

She is getting real close. The plenum is just sitting on the intake for now. This time around I'm going to set the throttle body in place 1st and hook up all the little lines and wires that go to it then install the plenum and mount the TB to it. This should make it easier to hook up all that stuff with my big ole' club fingers.
