Thanks for the input. Have a mild junkyard 5.9 magnum in my car now. Want to upgrade and was wondering the best way to go. Guess I will be looking for another magnum motor and building from there. Don't want to take the one out of the car as I like driving it to much and don't want to take the chance of not having the car to drive for an extended period of time. Being an old guy I have learned having the car on jackstands makes one tend to procrastinate and divert interest to other things and it never seems to get done.
