a lot of the elcheapo's are rebuilt in Mexico with chinese parts. that's easy to explain. but how can a domestic rebuilder be cheapert than a local shop with guys just earning a living and equal quality parts ? ? they can't. so you're trading precision and higher end parts to pay the common carrier freight that's how that works . bad idea by any measure but knock yourself if it sounds cool.

In addition to that it looks like S and J has a lot of "procedures" for their warranty, so probably don't stand behind it as easily as some. Regardless, there is some level of nationwide coverage that you won't get with a one off built engine at a machine shop.

So just an update if anyone actually cares 
. I decided to go with a local machine shop to fix the engine for two reasons. 1) there were no 315M engines available, so I'd have to remove mine from the truck, send it to the factory & they're essentially do the same thing the local guy at the shop is going to do. & 2) I get fixed what needs to be fixed vs. redoing everything - which I know also has it's advantages.
With the (hopeful) money saved I can do things like getting the tires I wanted.
Also thanks 5851a for the little note about shop hell. With Spring here & races in full swing, I'll definitely push for a firm date.

There are some mods worth considering while it’s there. Oil system and one piece rear main seal.

You'll be better off doing it locally. if they jerk you around on it too long just have them do the machine work and assemble it yourself it's not that hard to do and it might save a lot of time.
Better this way you'll know what quality parts you have and it won't be some minimum wage flunky who just quit Burger king doing the work.
