another grand for block, tank and machine work. So we are at about $4700 for a mostly stock rebuild (with forged pistons, assuming self reassembly).

Not a crazy amount of money these days. For reference, here is a bone stock 2015 coyote long block.
And the difference is, the Coyote engine is sold outright. The entire engine is light weight aluminum that produces 435HP right out the box. It features a roller cam and it is balanced.

By contrast, US$4,700 is a terrible price because you end up with a heavy cast iron engine that was assembled with cheap components, uses flat tappets and is not balanced. Expect 80,000 miles, like when the 1960 engine was new.

When I overhaul an engine I assume nothing. I take it all the way down, machine the castings, then use name-brand components and premium parts like, FelPro gaskets, Cleveite bearings, a true roller timing set, Hastings moly rings, Mellings oil pump and intermediate shaft, brass core plugs, etc. I also choose a proper cam for the intended service, and time it accordingly. My recent builds included roller cams for today's oils (so do OEMs). Expect 250,000 miles between overhauls, iike modern engines.

I'm not knocking Egge's offering, at least they have one, but their components are mediocre at best. Cast pistons in a naturally aspirated engine work perfectly fine but I use hypereutectic alloy aluminum with moly rings (and so do the OEMs).

The best combination (for me) is to source domed 430 pistons then hand pick all the other components. Curiously, the kits may be available including pistons but individually, their pistons are typically out of stock because the bundle fetches bigger profits. I guess they need to make money some how... - Dave
