Missed on this combo?

We're around 1000 ft above here. And the fuel issue is just another thing I was thinking about. Race gas and 33-35 degrees... right now I'm questioning everything.

Can't believe I forgot to check cranking compression. Of all things....and I can't believe my machinist didn't mention it to me. I think we were both just a bit shocked.

I can get back on the dyno pretty cheap. Might be a good idea before I started tearing things apart. If this thing had made 580 with a little more grunt down low, I wouldn't even have questioned it.

Might throw it back on the stand and check valve events. Another thing I shoulda done. Degreed it and just figured Bullet can't make a mistake so called it done.

If you don't get back to the dyno you will always question this in the back of your mind. Construct a game plan and stick to it.
Bring your compression tester, race fuel, headers with a 3" collector, different carb. Your engine isn't that far off and the curve has normal traits but what I don't like is that engine can't "clear its throat" until 4400-4500 for some reason. Cam and headers is where I'd look. Open the lash and see what happens. Record cranking compression before and after adjusting lash. Good luck and thanks for sharing BTW. J.Rob
