According to a article in Super Chevy magazine
"However, as well engineered and thought out as Grumpy's newest Toy was, the car seemed to struggle in NHRA legal trim recording high 9.8's at best while chief rivals like Sox were running at least a tenth to two tenths of a second quicker. As a match race car, though, the Camaro appeared to have found its niche as Jenkins would routinely run 9.40's with a big-inch "Mountain Motor" installed with all the weight out, but by then Jenkins was already moving on to bigger and better things."
