What RPM going through the traps with a 408?

Having fun yet? Good headers help air flow. You need 1 7/8" tubes. Your combination should be running 120+. I just ran @ Martin US 131.(Chrysler Classic) I went down to the quarter finals in the Pro class! Best pass was a 10.07 @ 131 & change in the "heat" and I mean heat! I have turned in a 9.98 pass this season @ Milan Dragway in Mid June. Car weight is 3055 with driver. Keep working your combination, you'll get the elusive 10 second pass soon!
