-----If you guys are talking strictly about 1965 Chevelles and 1965 Corvettes the difference is the cam, I believe. I dont have the specs in front of me, but the 201 Chevelles all came with a hydraulic cam and lifters while the 425 Corvette came with a solid cam and lifters. The 65 Chevelle 396 was the only instance in the history of rat-motors from Chevy that they put big-port heads and intake together with a hydraulic cam.
