With the engine still in the car I would plastiguage 2 journals just to have an idea.

The machine shop if not familiar with these dinossaur cars might have left the journal dimensions bigger than they should be for 0.0025 - 0.003 that this engine requires.

Another question : What oil did you use? 20W50 ?

If that machine shop is not familiar with the older cars (witch does not make sense if he is any kind of machinist) you need to find one that knows what there doing .Mistakes can cost a lot of money and time.Agood machine shop has all the equipment    to do motor work of all kinds.All motors old and new are very much the same except for specs and there are books for that.

The machine shop I use over here in the UK has books of specifications of all cars going back many years. He had the info on my 331. I guess the modern cars are on line now.

Sorry folks got held up with other projects/fires..!   >:(

Again thanks for all your input and details on this thread really good feedback.

Had a chance to polished the rod journals with 600/800/1000 grid wet just going slightly over them. I check the clearance and all were within specs between 0.002 and 0.003 with the new bearings, Service Manual states above 0.0045 would require to replace the bearings.
I did a quick check on the main journal bearings and the two center one were perfect. I check them with plasticgage and were within tolerance, Ive also slightly hone the cylinders.

Ive decided to clock the ring gaps at 180 degree between top and second compression as well as the oil rings with a 90 degree separation between them and 45 degree from the center pin. The black marks on the pistons are the guide Ive used to get them aligned.

Was able to get two in yesterday #3 and #4 it took me a bit longer by myself and with the block in the car still, so I raised a help flag for the family to help this weekend to get the rest in. Not sure how much this help will cost me or my wife in grandkids babysitting fees.  :D

Just need the time to get the heads over to the shop to be check and recondition.

The engine was done by a local machine shop around 2009-2010 and it sat on a portable roller for a few more years after it was done while I was getting the interior and body done. Im not sure what the old timer may had for reference at that time at his shop since he was a one man shop (with some temp helpers).   ???

What got me into this path was as I had mention above was the fouled spark plugs and smoking with two different heads (390 first and 365 now) on the engine. When I discover the rings were (IMO) clocked incorrectly and the gap was way above the specs. So only thing I can speculate at this stage the problem was caused by the shop, not sure if it was the owner itself or the helper whom assemble the block.  :(

Well finally got a chance to get back to putting the old girl back.

Got the heads back and torque down per specs, got the valve covers back as well to get the oil pump going. Yes, had to connect the oil filter lines before priming the oil pump.  ;)

Turn the crank by hand slowly while continue driving the oil pump to proper lubricate everything. Notice the oil getting to the hydraulic lifter so move to the next test.   8)

Compression test done to all cylinders now Im seeing at least 20% increase on all with a range of 175 to 185 on all, now this was done with no intake manifold and all cylinders were wet from the initial installation.  :)

So happy days are here again, I hope! 

Next task is to get the rest of the gears back in and do the burn in test, fingers cross hope for smoke be gone.  :D

The weather wouldn't scare me off Jose! Besides it would be great helping you out with your '56 . Strange as it may seem our weather has actually been very similar up here this summer. Very hot, with lots of humidity, then rainstorms. Working on Lexi the other day it was 95 temp and very humid with scattered thunderstorms. Clay/Lexi
