What jet and pv size on a 4150HP on SB?

Thats the same size primaryy and secondary jet and power valve on my holley 800 dp, on top of a 408 stroker, so yeah, you might be running a bit fat. What color is the smoke comming out of the pipes, blue/black, or white? hook a vacum gauge to the carb base plate, and find out what pv you need, kinda dependent on the cam in the motor.
