Many articles in past issues of the *Twelve-Port News* cover various aspects of GMC engine building. Tom Langdon has run a 302 with a stroked crankshaft (341 cid) and an original McGurk roller cam. A conversation with him about those things should be useful. A California inliner was running a supercharged 302 in a '31 Chevy, on the street, and was featured in the *Twelve-Port News* several years ago. i have not heard anything about that project recently.
i have thought that a full-out 302 for maximum horsepower and rpm (as opposed to the low- and midrange torque that is the great strength of these engines) would involve a 12-port head, fuel injection, and a "destroked" (3.8125) crankshaft from a 248. With .100 overbore that combination would yield 301.6 cid. With a supercharger one could think of 350 hp at 5500 rpm on gasoline. One might want to keep extra blocks and cranks ready to hand.
God's Peace to you.
