...Maybe it's time a consider a new hobby ...
John, I don't think there's an engine builder alive or now passed who hasn't uttered those very words... usually more than twice!
I think you've answered your own question regarding reman engines. The question now is, "can you find someone in your area that you can trust to do competent machine work?"
There really aren't too many things you need to rely on him to do at this hp and rpm level. If he can grind the crank down to the clearances needed for your new bearings (not just grinding .010 under and assuming the bearings will be correct), resize the rods, square the deck and head, align-hone that 4 foot long block and bore and finish hone the cylinders to the actual size of the pistons, you'll be far ahead of anything you'll likely get from another reman "chop shop". If he can do all of that, he can *hopefully* apply the same attention to detail to the valve job and guides.
You also won't be strapped to the same sh*t-quality China parts that the reman guys subject everyone to. You can choose your own pistons, timing set, cam, etc., all of which he can likely order so you don't offend him.
With just a couple of specialty tools, you can do the assembly yourself at your own pace and there are plenty of guys here to help.
The cam alone is something worth looking into. If you go with another reman engine or even let the shop choose some typical "replacement" cam, 99 times out of a hundred it'll be ground on some old, soft core with the accuracy of blind monkeys throwing darts and you'll have to break it in and hope it lives with today's crappy oils.
I just learned last week that Comp doesn't even grind a large portion of their catalog cams. Accuracy is all over the place and the cores are typically too soft. If you go custom, you can at least specify the core and any additional hardness treating you want done and Comp will actually grind it. If what I heard is true, Lunati is pulling the same thing. I guess "imagine that" as Comp bought Lunati.
Can you milk this thing out until the weather turns? It might be a cool winter project while you're parked anyways.
