Reply to "CHI 3V Single Plane Intake Needed for Dyno Project"

Hey, yes I do have a spacer and the reason I can have one and still clear the stock screen is because I run fuel injection and the throttle body is shorter than the carb. Also the weiand manifold 7516 fits the heads port size almost perfectly. Where as the 7517 is for the 4v heads and the ports are to big and will not match. I'll tell you I have run this manifold for years and it is great. At pocono I ran around the track in 3rd gear at 7400 rpm with no trouble. That year I was having shifting problems before I rebuilt my ZF myself and just used 1st 2nd, and 3rd . For you with a carb you should see which is better because with fuel injection the manifold is not as important. But if you intend to run on the street I'll bet the weiand would be much more of a pleasure. If you ran the 7516 and did not care about being under the stock screen then you could add any amount of spacers that you liked ,to make the plenum larger to get you carb higher up from the plenum floor for better fuel distribution and high end power. By the way CHI did the spacers for me as part of the regular price of the heads. If you need any more info let me know.
