By 1970, Grumpy's very successful 1968 Camaro had seen over two years of heavy racing and was pretty much used up and no longer competitive. Chevrolet had just came out with the restyled Camaro for 1970, so 'Da Grump built one.

The big-block Camaro looked fantastic but was as inconsistent and troublesome as the Hemi Mopars were fierce. After two years, Jenkins retired the car to build his tube-framed small-block Vega. Eventually Jenkins leased the car to Bruce Larson while Bruce's Vega Pro Stocker was being build. After Larson was done with the car, Bill sold the '70 Camaro to New York racer Richie Zul. Richie thrashed the car like crazy and surprised many with some amazing performances. Then the car simply vanished. For the longest time, rumor had it the that some people who didn't like Zul dumped the car in the Hudson River.

Then in 2002 or 2003 the car was for sale on eBay of all places, ending the rumor that it had been stolen and dumped back in the '70s. The last known incarnation of the car it had been painted all white and was used as a street racer. One thing is for sure, by now, it must be one beat up hulk of a car.
