If a true GM Performance "Rocket", it will be fine. That was Oldsmobile's "version" (thus the name "Rocket") of the 400SB, raising the cam and using the BBC timing set. The tall deck allows for longer connecting rods, a "must" for high RPM durability. Several years ago, we built an 1,800HP blown/alcohol 434 using the Rocket block and "splay valve" heads. 9,500 RPM, lived fine, went 6.60s in a LWD.
