What is a good combo for turning high rpm?

That is just what the total cost was for parts, machine work and final dyno testing. Nothing super trick in the engine, but it does add up. I kept a spread sheet and filled in the cost of each part. The total spent was over $19,000 for parts and machine work but a few things were done twice so I rounded down the final number to about $18,000. I didn't include anything for my time though and I spent a lot of hours on the CNC mill removing material. So if the engine had been built at a professional shop I'm pretty sure the final bill would've been over $20,000.
