and it isn't an actual 'classic', the Corvair mentioned in my previous post was a notorious sleeper in my circle of car geeks.
My friend took the 350ci small-block Chevy from my Z-28 and used a Crown Engineering Corv-8 kit to create a radical little street racer.
Because the Corvair sat lower to the ground that most muscle cars, potential victims could easily look down into the passenger compartment and see the V-8 mounted behind the front seats. This was not conducive to getting money bets from other gearheads...
To solve this problem, several old suitcases were cut up, pop-riveted together, lined with heat shielding and used as an engine cover. Routing the exhaust thru stock Corvair turbo mufflers made the thing almost whisper quiet. Drivers looking into the 'Vair now saw only a wimpy-looking, faded beige grocery getter that looked like it was packed for a trip to visit Aunt Tillie...
The look on the other driver's face as a Corvair smoked his 383 MoPar, GTO, etc. in first gear and went slightly sideways as it checked into second was hysterical...
