I’ve built a couple bbc marine motors and a turbo Subaru. The crank checked out and was polished, rods cleaned up, cam checked out. Pretty much a stock build 215 motor. The pump is getting sent to DPE soon for a max, balance and shined up.

It’s going into an old power wagon. The guy wants it to run with low smoke , and not leak. Figured I give it a shot just to build one before I do my 12v. I also picked up some billet oil squirters from contagious diesel since some of the factory ones were busted.
 
I haven’t picked up a new oil pump yet or head bolts. The truck already has 4ks thinking about 5x12 injectors. 24v oil pump is a good upgrade right ?
 
ATF and LINT FREE rags or paper towels, wipes all bores/journals until everything is clean
 
They did. I usually spray out the oil passages with brakleen and compressed air after I get a block back
 
Lacquer thinner to clean the bores, journals and deck. 15w-40 in the bores to lube them for the pistons. Some kind of lint free towels to do all this with. And good assembly lube.
 
I always wash with soap and water, then blowdry it. then brakekleen on a towel in the cylinders til it comes out clean.
 
HOT soapy water (Dawn) in bores first to get out any grit and I mean HOT then oil...
