Nice! The engine guy will check the other stuff, I'm not really set up to measure for journal taper and stuff like that. So far so good..

Thought I'd update this....brought the short block home from the shop a few days ago. I'm waiting for my timing set and a few other goodies and then I can degree the cam in and start buttoning things up. I'll get it painted and then it will sit until I decide to do 'the swap'...when that happens the car will be down for a bit while I get the heads cleaned up, measure for new pushrods, stuff like that.
Clearances came in at .003 mains/.0027 rods/.022 rod side play
.005 piston-to-wall/crank thrust is .007
A wise mopar guy whose name starts with a D and ends with a V and a W once said, "if your clearance is loose you'll know, if you're tight everyone will know"....so I'm satisfied with the numbers.
As far as the 440 Source kit, the machinist reported very good fit and sizing as far as the
rods/pins/crankshaft. He did kiss the bottoms of the bores for some extra breathing room, even though he said it may not have been necessary, he just felt better about it. The oil pump boss needed a lick as well...other than that it went together nicely.
P.S....
Another tidbit of info from the machinist. To get the decks square and the pistons to zero, he cut between .008 and .016....the pistons by spec are .010 in the hole with a factory deck height, so the decks actually varied from .002 under to .006 over the factory spec to start with.

Got the cam (spec'd by PRH--thanks Dwayne) in and degreed. Of course, there were tight bearing issues. Had to break out an old 'cutter cam', oh well it turns smooth with just finger power on the bolt heads now. (Dura Bond PDP-17s). It didn't spin for **** at first. What else is new in big-block mopar land
Anyways with the cloyes race billet timing set it fell right in at the card specs on the zero dot position..and good times were had by all.

Custom Comp solid flat tappet. The card, with all my chickin' scratch....
I tend to go overboard with the checking but I enjoy the degreeing process...quality time lol. I checked durations at .100 and .200 and more timing points on both lobes but it looks like I didn't write those down...like I said, a little overboard!

I always enjoyed doing the cams on my drag bike. Twice the fun. 110/114
