Thanks for the data! Those are quite similar parameters to my initial try (1200, 24/34 in by 3000), except that I didn't have .110 holes in all four plates. With 3.91 gears and 295/50R15 tires, I will also be cruising at 3000+.

I have noticed that this cam idles smoothest at 1200 also, although it will tolerate 1000 but a fair bit lumpier.

Would you recommend the four smaller holes over two larger ones? work
I'm thinking that if I screw up, I only have to repair or replace two blades wink
