This is the Big, Big Brother of our Pro Open engine. Same internals and parts, except the block is machined and sleeved to accept a 3”+ piston, with a 2.400″ billet crankshaft.  The Tillotson block is standard equipment here. There is no substitute for cubic inches, and we take full advantage. This is the King of the Small Block Open class. The DED head is the best billet head on the market and makes this powerhouse even better. Billet DED valve cover is included. Comes with 32mm carb and custom header package.
