    I found a NOS, discontinued Spectre air cleaner housing I have had my eyes on. $250 at Summit when Spectre last offered it for $150 on Ebay and it comes with the re-useable 14x4 air cleaner. Seller still has 8 showing available at this time, just FYI. I found some large scoops listed for saw dust collection, that I plan to fit into the front core support on each side of the condenser. Also found some 4 layer, insulated flexible 4" duct that looks like the single layer plastic intake tubes GM used on the 70s and 80s vehicles externally. Thus it is getting a dual 4" cool ram air intake system. Should help out the intake air temps a lot on a hot summer day preventing hp loss.

    My plan is to tape off the lid and paint the sides and bottom with universal semi gloss black engine paint, leaving only the lid shiny like the old LT1 or Z/28 350s.
