We had a customer with a .060 over Merc come to our shop for some dyno tuning, the car had stock manifolds and exhaust. Cannot recall the entire build of the engine other than a dual manifold. What I do remember is it made right at 83 whp. A few months later he called us up and wanted us to re-tune it for his dual exhaust system. It had a set of tubular headers and some glass packs. We strapped it down and made a few pulls...timing was good and air/fuel was spot on. It made 82 whp that day...the reason? The weather. Our first dyno session was early in the year, the second was right in the middle of summer. I always wanted to get that car back on the dyno on a cool day for an apples to apples comparison. I have stock manifolds on my 36 with duals and some no-name glass packs. Its all about the sound.
