Is this an L6 application?

Re: Need help, 4 barrel on offenhouser intake.

Either the 390 CFM holley(P/N 0-8007) or a 500 CFM Edelbrock are good combos on the inline 6s. I had the Edelbrock on a built 250 with a pretty radical cam. You'll need to get a throttle kit to make either carb hook up. 12bolt Tom is a good resource for the 6s.
