What camshaft spec for 425 hp

I still have adjustments to make on my carburetor, every now and then it will pop out of the carburetor on the Launch, it got better after I change from the red to the green accelerator pump cam both were in the number 1 position and changed the shooter from a .031 to a .033, when I was at the strip it did pop on one of the passes off idle launch’s. Any suggestions where to go with the carb adjustment?


I would use the blue pump cam and most likely a 37 squirter. Also, you will most likely need to adjust the accelerator pump arm for the blue cam so it is in the correct position with the throttle closed. You may have to do that with the green cam too, but it’s been so long since I used one I can’t remember. Dan you take a picture of your green cam?
