nice truck man what year? anyways my specs are a 1968 f100 with a 400 modified with edlebrock cam, intake , a holley street avenger 670 cfm ,and yes i have a spacer,but his 454 did not run very good most of the time, also he told me he had adjusted everything on it..but he kept saying how the float level is fine. But im not sure of the holes on the intake yt i am at work so i will check when i get home.. Thank
