I don't think that was a stock offering. Did you buy it because you have a use for that motor, or just because those motors are currently popular?
Since that's not an original motor you might pull the motor and replace it with a 350. The 350 could be dressed to look original in that truck, but would give you the advantages of modern V-8 power.
