lol , if i win the lotto i will rebuild the whole car and the engine and just rebuild the engine with semi tight clearances so i can run a cheap 15w-40 HDEO
but that won't help, likely the limit is in the rigidity of the block and cranck. You need more clearance if you want to run high RPM, not less. Recipe to spin a bearing, that is...
If i rebuilt it i wouldn't probably throw any performance bits in it, i'd keep it stock like it is now , i never rev it past 4750rpm, it has a lovely flat torque curve so you can just lug it around in 2nd or 3rd all day if you want to really.
