Both my Indy headed 422 and my present Edelbrock headed 408 ran 5.98 with my son driving and 6.0 with me driving. My 422 ran 9.37 with me driving. My 422 had a solid lifter cam and a 850 carb and was out of steam around 1000 foot. I predict it would run 9.30 if not a hair quicker now with the roller cam and 1000 cfm carb.
