I was lucky to find that old carb hat for my 390 Holley, the filter box was from a 4.0 jeep, I have to say it helped more then anyone could imagine :thumbsup: cool fresh air being delivered to the intake made my little /6 very happy, where I put the box there was already a hole to keep the battery cool, I moved it to the trunk . I will be looking at using it with the 360 if I think the filter will be big enough for the 360
