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.

Here’s a past thread on the main support girdles.
