273 dilemma

the early 273s had very lightweight bushed rods and I think those ended up being used until ~69/70 in the 318LAs. By 73 the 318 was using the 340/360 rods but press-fit pins
Those later rods look nothing like the early rods.
I have available, a low-mileage 65 273 crank for the early rods, that I got in an engine back in the early 70s but it will need to go to the machine shop cuz the last time I saw it, it was a lil rusty.

Some say a guy can drive to Calgary from my place in a day, but I know for a fact that I can't ride it on a Motorcycle at any legal speedlimit and not fall asleep trying lol.
Google says ~13 hours.
