Starting engine assy.
I got my stuff back, and now have begun engine assy.
If anyone has followed my other threads,

you can follow up with this one.
My engine was taken apart for Preventive maintenance, and needed to have the crank turned, bearings replaced, and new rings, (and a few upgrades to go a little faster)
After washing the block with Dawn and Hot Water, at least 3 times (checking the interior of the block with brake cleaner soaked shop towels) it finally appeared to be clean. I then sprayed everything with WD-40 and blew it dry outside with compressed air. Moving it inside, the block dried out really nice. I had the air conditioner set at 60 to take the humidity out, and the heater set at 65 to keep it dry and warm. It was only 60 here in Mich. yesterday.
Putting WD-40 on the whole block, in and out kept rust from forming. And its clean, just bare cast iron. I left it on the engine stand overnight, and put a lint free towel (if there is such a thing) over it. This allowed the air to circulate and dry everything completely, I didn't think a plastic bag would allow that.
Today I started pre-assy. of the crank, pistons, and rods.
The crank was turned .020/.020 and magnafluxed. The rods were magged, and cleaned with new rod nuts, and the pistons were re-hung after cleanup. The mains are .002 clearance, and the journal surfaces look like a mirror. The rods that I have in are .0015 for #1&2 and .002 for #3 using plastigage. Side clearance is .018 for 1&2 and .020 for 3&4.
I measured the untorqued length of the rod bolts (ARP's) and torqued to stretch at .006. This required 45# of torque. I plan on getting the rest of the pistons in over the weekend.
Questions for you guys:
I think the side clearance is a bit on the high side?
And I have gone with the same high volume oil pump that was in the engine previously.
My machinist said it should not be a problem to run it.
He also said to redline at 7200. Sound a bit high? I was at 6500 before. It has the later small journal rods in it. The rotating assy. has been balanced, and magged.
