Machine 360 crank to fit in a 340 main block

Just my .02 take it for what it is. At the price of crankshafts now it would be better if you just bought a new crank. I had a SB mopar crank cut down for a SB chevy jod journal. It cost me 380 bucks plus shipping a heavy chunk of iron, just to have the rods cut, widened, and nitrated. If you look at that the price a new Eagle crank is less than $750. I understand that the rotating assy is an odd stroke it just dosn't make sense to me to spend $600 to have a crank cut down and rehardened even if it needs to be reballanced. Sell the used crank and use the money to buy a new one.
