Update
Block and head are back. Cost me $600.00 for one sleeve, deck job, hone all cylinders and hot tank. Cam bearing are pristine.Crank and main bearing's like new
Head was $1200.00, price included $500.00 for a good core. All new intake valves, seats and springs. I highly recommend PMS machine machine in Spokane. Quality work, fast, price was super, and all the people there are friendly.
Total, $1800.00 and change.

Power Machine Service, Spokane Washington

Crank is already in, rods and pistons next after I paint the block.
Plan to enter it in the Oakland roaster show when done!

Great work, do right and you do it once. That block looks so tiny vs the 10.6l 3208, but then again I have not seen a naked 3208 block. Cat numbers make no sense to me, how many liters is that motor?

3126 is 7.2 liters. HP to 330. Torque 860 lb-ft @ 1,440.

Funny, it does look small like a chevy 6 cylinder, but it isn't. And it is heavy too.

Hope we can remember where every bolt goes. Got a million of them Bruce.
I put them in groups, and labeled the can's. But there is still a ton of them in each can.
At least everything is clean and nice to work with.
Once it's in, a million hoses.
Still better then paying Cat 20K+

Old cat mechanics mentioned the cat yellow paint held the oil links in. Paint assembled?

I have heard that too. Probably because a couple of parts have no gasket, just sealer, and the rest is O rings......Everything is painted, put going to paint complete motor when done again.

Piston, rods and head today. Head torque has to be at least 300 LBS. Took some big wrenches.Motor is pretty much assembled. Spins over nice.
Look at the pictures close. You can see the 3rd unused lobe on the cam, probably for the next generation 3126 A three valve engine.
Should be installing it tomorrow into the coach completely assembled.
Check out the pretty ladies all in a row! Not jay, he is my racer friend helping!

Nice, sanitary work. Sure it will run well. Some shops throw a lot of used parts back into a overhaul. Yours is more like a re manufactured engine.

Thank you, best part is, we are ck, ck, and triple checking every thing. Most shops blow it on something. I am always disappointed.
being a drag racer, I can't see losing a race Mickey Mousing's something. I hate working on my car at the track.
I bet it starts up, and runs perfect from day one. As I mentioned before, engine looked perfect inside. Just a stupid $10.00 oil ring fail.

Lot a great satisfaction when you turn the key and it roars to life, checking and rechecking keeps the pair of noids away.

Extra cam lobes may be for vibration control on an inline motor, what's the latest and greatest assembly lube?

Ever so close. Maybe one more day. Picked it up with the cherry picker to turn it around. No issue's.
