Well, actually I plan on putting on a performer rpm intake and an edelbrok 600cfm carb (4 barrel). That's with out a spacer.
I wasn't sure if the new intake and carb (with out carb spacer) would be taller than the old factory stuff (including carb spacer). Also, I do have dual exhaust and headers. The pipes currently end right after the mufflers
I need to fix that.
