Well since we are here talking about this engine I might as well jump on in. Trout Two, this new manifold has come about by EFI-DIY because he was trying to help others who do not see this new fangled EFI as a gift from GOD. They have worked with carb's and are very comfortable with that technology. I'm a hair shy of 50 and have work in both areas but I would not down the guy's who, after all have carried the torch of HotRodding for us to get to were we are now. If they see merit in this engine but, don't want to mess with the newer technology of EFI then let's see how they can work with part of the new but also use the old. It would be a great start for even the adventurous to use two 1bbl TBI units as a stepping stone to Mulit-Port EFI.
