OIL MODS
BTW, I didn't mean that the Guitar Jones stuff is BS. I haven't read his thread. I meant all the nonsense of turd buffing everything on the outlet side of the pump. Make the holes bigger, get the volume there with enough pressure and that's most of it. You don't need a cross over tube or none of that.
Again, the big gains are on the inlet side of the pump. Make it big. If you want to go past 8000 and make power, you need a dual inlet pick up. I think my pick up is 1 inch. Damn near made it dual but I'm shifting at 7000-7200 with this engine.
One last thing. If you are serious about RPM and making power up there, you can't use a passenger car block. Even if you fill the block they move around way too much under load. You end up making the clearances way too wide to keep the block from grabbing the crank, and that opens up a bunch more problems.
