422 dyno fail

No engine builder worth a damn degrees a cam by the TDC mark on the balancer. In fact that’s not “degreeing” at all. Please explain to me how you would set intake centerline with a balancer. I’ll wait. You have a very long list of credentials on your website, it’s amazing to me to read some of the comments you’re making here.
I have checked the intake centerline on complete motors to verify that it is or is not the cause of a poorly running engine. First verify tdc is correct on the balancer with a piston stop. Then connect a dial indicator to #1 intake pushrod. I use the .050 before and after method. Mark the balancer accordingly. Mearsure the circumference of the balancer. Divide by 360. Now you know distance in inches per degree. Measure and do the math.
