Either one will kill you in a heartbeat. But... you might consider "splitting the baby" as I did with the 4.125" SCAT stroker crank. With an aluminum flywheel it ramps up as fast as you probably would want. Getting 6500RPM from hydraulic lifters could be tricky, though. You might want to consider solids.
