We're getting ready to rebuild a '63 Stude 289, and we're trying to find out what kind of speed parts are available. It'll be a street engine, not a drag racer, and we'll be running an Avanti Paxton supercharger. I've found quite a bit of information (here and other places) but a lot of it is old and out of date. (Lionel Stone, for example, has retired and may have even passed away.) Specifically, we're wondering if we can get roller rockers, or at least higher ratio rockers, to start with. One source implied that we could refit to stud-mount rockers (which, we assume, meant Chevy) but gave no details. Second, does anyone make a modern cam, or are we stuck with R1/R2/R3 regrinds? And along with that, can we get hydraulic lifters? Lionel had a kit- reground cam, hydraulic lifters, new pushrods- but as I said, he's apparently out of business. Thanks. Doc.
