Nothing too crazy, as you see here:
2007 Lawnmower 3.5HP
1975 CB750
1973 Pontiac Formula 455
1978 Ford BabyStang 2.3L
and my daily driver :
1972 Dodge Monaco 360, taken 2 weeks ago.
That baby stang is my teen daughter's car, ain't too fast off course but we made it fun. Got a 60 over 2.3 with a monstrous 450" lift cam that the 120 PSI can barely spin, Hedman headers to a Flowmaster 44. Idles like a V8, revs like a moped. She loves it
... if you can't go fast have fun with the engine music at least.
My fav pics of that bucket :
