I can feel it lay down toward the finish line too. The timing total is 34 degrees, carb jetting is 74 front with power valve, 84 rear. Still wondering about putting the cam straight up instead of 4 degrees advanced. Thanks to all for answering.

Definately wouldn't stand the cam straight up.
Cam is just real small and is barely opening the valves maybe 1/2 inch if that after deflection.
Small cam and small heads on that many inches is a governor on performance, you are running real stout with what you have.

yeap I agree with some other post 1 no where near enough cam, need more head work and more carb and I will tell you I was running 4.88 gears with my 416 and it was very happy.

Make sure your fuel delivery system is adequate. Good fuel pressure all the way down the track?

What does the car weigh???
Did you run it open headers or full exhaust??

Yes I run open headers and the car weighs 3100 without me. I'm not sure of the weight but I weighed it once on some grain truck scales that were certified but made for weighing a lot heavier stuff, like a dump truck full of corn!
