Zl1 #56

#56 was one of the few ZL-1's to actually say ZL-1 on it

Chevy was trying to make race cars without looking like they were making race cars

In other photos , the "ZL-1" was not on the fender.

I have read some interesting stories about how Vince Piggins was really pushing the dealers to race a ZL-1 in 1969. He went around helping to put together a dealer with a big name driver including Funny Car drivers.

Vince would also show the dealers how they can make a lot of money selling hi po parts by running a drag car with a lot of viability at the local track

Vince also helped out some of the racers using the engine warranty program. One guy said they blew a ZL-1 engine and Vince sent them a new complete engine. He was surprised because normally they gave you a hard time on engine warranty if they knew you were racing the car.
