Edelbrock head and ported Indy intake
Sometimes the hardest person to please is yourself. When I start out flow testing an intake I ported or in the process of porting I will usually test an inboard port of the intake. (3-4-5-6) because if I can get good numbers out of them the outboard ports are usually a cakewalk. The numbers I posted above were from number 4 runner. Although ok I hate the way Indy intakes, super Victor and a couple others leave a ton of material that shield the inboard runners. For the test above I cut down the divider about 1/4 inch to open it up some. It worked but while cutting down the other 3 dividers I get the bright idea to open the plenum up some. I wish I would have taken better pictures but between the ones above and this one you will get an idea how much material there is.
