The way it was told to me on that dark, cold December night ... heard they (chebby peep's) used the first porcupine headed 302 in the Poncho, because they new it would be slap'd hard with penalties and Chevy could step up the R&D of the 302 without getting docked the manufac.'s points, and have things ironed out by the time Chevy used it. Dang Smokey Yunick!
I'd rather see a rust bucket on the road, than a garage queen anytime!!
