Thanks Ted for the article "585 horsepower" in the new Y-block magazine.  A few ( a bunch, really) questions on the main girdle ; how thick, steel or alum.? Are the studs ARP's and what application? Is there a gasket between the girdle and the block or just thin sealant? Are there spacers between the main cap nut and the underside of the girdle?   Barry L.

Paul.  This engine requires much higher octane fuel than you can get at the corner store.  In this case, Sonoco 110 was used.
