I do have some tests I started @ 3800 but If I remember right I ran the car from 4200 to 5800 on the track. I really didn't want to run it past 5800 until I went through the engine, after its freshened you can be sure it will be run much higher than 5800, in fact I need more RPM to make the driveline changes I want to make. I do have the top end off the engine now and everything appears to be legal. When I look at whole combination of car and driveline and engine I can't imagine not being able to make it faster. I will mention while testing I leaned the carb down, I had a 67 jet with a .062 rod and it picked up from the race setup and I had no jets or rods to go leaner, I test @ 6400 feet elevation. I will look and see if I printed any of the tests starting @ 3800 RPM, if I have them I will post them.
