Want to keep that old crossflow propped at 5500-5700 rpm WOT. Try a 17 pitch and check your engine height and also insure your motor is adjusted correctly/link and sync - timing and such,,,,you keep running it 4000 rpm and you will destroy it. Carbon up your rings/exhaust/chambers to name some issues. They don't like to be lugged at 4000 rpm.
