440 Intake for Full Race?? - Our Lil Red Express

I agree on the leak down. I leak test mine a couple times a year, not hard to do and gives me piece of mind. If you do have issues with rings and need to freshen up your engine It maybe a good time to improe your combo. IMO it sounds like your are leaving some efficiency on the table and a sheet metal intake is not your combos future. Post what you have now including the drive train, there are a lot of good racer here that can help.
