That filter is close to the same as a lot of LT1 Corvettes, Camaros, Firebirds are using. Looks a little small maybe, but the inside is also exposed, so its almost double what it looks like. You could also hook up any type of element in the well. You could use a square box with square element like in most cars these days. Im told the 3" tube is sufficient for almost any carbed engine. I thought maybe the Jeep cover may be restrictive too, but didnt notice any performance change. It was on I think a 318 Jeep V8, and we know stuff like that is always overengineered by manufacturer. My engine is 383 cu in, and it dont seem to bog at all from lack of air. In fact, seems more responsive than before. With V8s in these cars everything is experimental
, I didnt want to add scoops or holes anywhere just for an air filter, but thats just me.
