    She had .395 lift cams, lightened flywheel, Koni suspension, port/polished heads, 11 to 1 compression domed pistons, and the engine was a D16 (twin overhead cam). For shits and giggles, a 75 hp squirt of nitrous as well.

    A street legal go kart that was a better car than I was a driver.

    I wanted to post a pic, but my internet is all wonky. I'm blaming Ajit Pai.

    Grand National vs. GNX--the GNX stood for Grand National eXperimental, and the ~550 cars were built as GNs by Buick and shipped to McLaren/ASC to be turned into GNXs. This was available only in the car's final year.

    the thing as, when the GNX came out, GN or t type owners were already deep into the kenne belle parts catalog..bigger turbos, coolers, engine blocks and cranks 'corrected' to use wider main journals...there were even wicked 4.1L versions (buicks forgotten v6)... If you were not 12's or less, you got made fun of.
