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.
Gear the car where the engine wants not where you want it to run.
