Question about the 4bbl intakes

Many posts on this w/ photos, so use search. Yes you can, but not trivial. Some carbs will need a different throttle cable. You can use an automatic, especially if you get a Lokar universal kick-down cable. A 4 bbl will help a bit if you also install a bigger exhaust and/or larger intake valves and high rpm cam, but don't go too big. The smallest 4 bbl you can find is best (~390 cfm).
