Mechanical, yes. The Crane Cams Musclecar series
P/N 969961 (or
P/N 968561 if you want to go even more HP).
Hydraulic, no. The closest you can come is the Crane Musclecar series
P/N 969391. It's actually the replacement for the Camaro, Chevelle, Nova, etc... 396/350 and Vette 427/390 and 427/400 engines. I put one of these in my car a few years ago when I grenaded my other cam and really love it.
