I am doing the same thing with my 72 c10! I got a rebuilt 230 with only about 1K miles on it (or so I was told) for very little money and am going to put a 700r4 behind it as my 59 1 ton is my big horse. With coil springs, A/C, and a hydramatic this baby will be my caddillac!
I had a 68 camaro with the 230 in it and that was about as an indestructable motor as I have had. We ran it out of oil when an oil line failed to the point that the engine stopped from overheating. Figured that motor was toast, however, we plugged the line filled with oil, and it started up and ran like it always did. That sold me on chevy 6's. Ran the poop out of that 6 and it never put me on the pavement.
I am just about to go get that tranny as soon as I clean up another few projects. The truck originally was a 350/350 combo.
