Junkyard Magnum Motor Finds
If you pull one from a wrecked vehicle, check for obvious damage caused by the collision.
Broken engine mounts, or frame pushed into the crank pulley etc.
Bought a 2.5 liter once out of a wreck for my wife's Daytona.
The doner engine came from a car hit pretty hard on the drivers side.
I had to constantly put timing belts on that car, my guess is the end of the crank had a slight tweek to it.
It would eat a belt about every 5,000 miles.
