Checking to be sure all the pins on the bearings line up...all look good! I'll be assembling this weekend so stay tuned...

Update for the weekend...got the crankcase all torqued up. No problems so far!
I love knowing that all the external fasteners are stainless now. It was kinda expensive but damn it looks good!
Runout on the crank is 0.002".

Time for a little bit of cylinder deglazing

Does anybody have an opinion on if I should trust these SBT wrist pin bearings or reinstall the used WSM bearings?

Well I went ahead and used the SBT bearings. Hope they last!
The cylinders are now on and torqued. The torque wrench adapter worked perfectly and the stainless nuts look really good too.

Finally got some time to work on the engine. I have the intake manifold, gas valves and cylinder head on now so I was able to do a leak down test. Do yourself a favor and make some block off plates. ...make the test so much more reliable.
Anyways, the first test I was leaking about a pound a minute. After spraying some soap water, I saw there was a leak at the block drain bolts. I guess there was some powder coat on the sealing surface so all 3 were leaking. Cleaned off the sealing area with my Dremel and they are good to go.
Second test I was getting about half a pound every 2 minutes. More soap and I saw the exhaust valves were leaking. I pulled them off, used some silicone on the gaskets and buttoned it up.
Third test is only a pound every 10 minutes with exactly 2 pounds after 20 minutes. I say that's good for me unless someone thinks otherwise.
I'll pull a vacuum tomorrow to see how it goes.

Finally! The engine is in! Alignment was still dead on even though the engine has been removed. Time to run some water line for the exhaust manifolds then the pipes are going in.
I also painted the flotation foam black because they were pretty nasty before. Looks pretty good I say...hope it holds up.
