Saw a Boss Hoss (350 Chev small block) - with a 509 horse nitro kit on it at Americade last year. No wheelie bar or anything. There was a Boss Hoss trike with it done on a '55 Chev theme. Robins egg blue and white. Very nice.
The 750's were wild in their day at over 12 seconds. Any current 600 sports out of the show room would kick their butt.
Keep the rubber side down,
