From what it sounds like, your money might be better spent in a Pontiac motor. With all the time and money you are going to spend making that motor work, you could invest in a nice Pontiac motor and put that money into making a stump puller out of it. I thought of the swap before and was told by many engine builders that the Cadillac crank shaft is very thin and does not hold up. Supposedly it was notorious for being a weak point of the motor.
