Air Induction- The Real Scoop

[L_e_e]

Here's my attempt at a cowl plenum ram air system on my 74 Z28, using a early 90's GMC HD truck air cleaner and a repo open element base, I lucked out that the factory chrome Z28 lid fit perfectly on to the truck air cleaner. At the same time I also installed a cross ram base with a single 4bbl so I don't know if there were any gains in performance from the cowl plenum but it sure sounded good and looked almost OEM cool which was my initial intent.
