What camshaft spec for 425 hp

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?
