A previous poster was inquiring about which 4 barrel intake for a 6.1 had the shortest height producing the most hood clearance. Someone stated an intake that did this and he used the abbreviation ATM. I'm not familiar with a brand that is abbreviated ATM. Thanks for your help.
I think that might be short for "at the moment", mean it was the shortest intake currently available. Don't think it was a brand or anything like that, at least not one I've ever heard of.
