that early 392 hemi isVERY heavy. be for you put it in get the heaviest torsion bars you can get. i put a early 392 hemi in a 1959 ply. it was so heavy i had to cranked the height bolt till it bottomed out. that made the rubber bushings pound out. above all do NOT bottom the adjusting height bolt. AND it will not go around a corners any more. it will weigh 200-300 lbs more than ANY engine that the car is made for.
