I recently answered a thread about hood clearance, with rpm air gap intake, with Holley ST. Avenger carb I believe, with 340. I told him mine just cleared, but breather nut was just into insulation, No prob imo. I`ve been recently researching thermoquads and read a good point, that didn`t occur to me, at install. Concerned mostly of clearance of hitting hood. The author warned of drop base air cleaners and choke towers being too close to lid causeing ritch idle due to lack of space and airflow. Well this got the greymatter churning. Sure enough I had to use EDE. drop base,2.5" K+N element, actually 2.25". I checked operation of everything initionaly, and that all choke componets operated freely, They did, BUT, upon closer inspection, I can see when choke blade is fully open, its rubbing lid. I`ve come to the conclusion, this baby could use more air, but I`m at its limits. I have an 1/2" spacer but prefer to keep it for isolation purposes, mainly. Also long duration cam will compound Idle signal. right? I`m open to all input with this grief. I have a spare hood and willing to go to scoop, but like the sleeper look, Would rather keep and try to use and work with what I have. Then try to adjust or modify carb once breather clearance issues are resolved, and maintain streetability. Heck if I had a scoop I`d run a 5" filter if possible. I`d appreciate input and Pics of all you guys 67-8 barracudas with hood scoops of any style, with exception of chev cowl induction, even though I finally got to see one in this forum, Looks pretty good but Id preferr a factory style scoop8-[ Another thing that concernes me about scoop is getting caught in rain:angry7: If anyone`s running a modern fresh air system, can you give a measurement of base to top of hat? thanks
