273 swap to 318/ build, cost, potential, daily driver

you can probably add 350 to the machine work bill on the heads for new hardened exhaust seats, and probably a guide or three, and unforseen things and stuffs. a new crank isn't all that difficult to source, so the cost of that (free~$150) + whatever they need to do on that (hopefully just a polish). then cough up $700(?) for pistons and rings, plus a bore and hone at i'd guess another $400 unless you can get away with just a hone and rings. if the rods need resized? there's another $200.

double the price on the waterpump and timing chain to get actual decent parts that will last.

Good advice I appreciate the input. I’m hopeful for a hone and rings, after its rebuild in 85 it was not driven much thereafter. Still clean clear crosshatch in the cylinders. So aiming to use my pistons and avoid any unnecessary machine work. I’ll call a few shops and see about having the crank polished. And yes good point in higher quality parts for water pump and timing set. (There was very LIGHT surface rust in some of the cylinders, I know rust is rust, it washed right out with some PB and a maybe a minute of cleanup with a scotch pad)
