for my 2316 it seems that the stock plenum might be reaching it's limits as far as volume goes.....so, I either fabricate a larger common plenum, or go with individual throttle bodies such as TWM or Jenvey*
single plenum would be easiest, but the individual throttle bodies look better (IMG:style_emoticons/default/smile.gif) has anyone switched from one to the other on the same motor with everything else being the same??? *Jake Raby is the U.S. distributor of these.... |

Aaron, I was thinking along those lines last nights as I have a set of carb manifolds on the shelf. Just need to get some tube bent, weld on some flanges and bolt that to the manifolds. The plenum could be anything and weld on a TB. The sizing is the key as how big should stuff be?? The 3.2 looks way too big! I read that the runners should be about 10% larger than the intake valve or velocity suffers.
