Well to me, JMO, a roll bar would of put a damper on the look it with the vert down. Of course guess you bought it to race it, what it was built for, that's cool. My 55 has a 4.11 rear, mini tubbed 11 1/2 inch tires. A cool look with Cragar's.
It is a street terror! A little less quick with the gear change but still plenty fun...Dyno over 500 HP and torque. Engine built by a Circle track engine builder....Boggess engines.
