Build Your Wildest Wedge With Bill Mitchell Products’ Aluminum 440 Blocks


No doubt you’ve seen many of the updates, full-length features and news articles we’ve published here at Mopar Connection Magazine on the awesome aluminum Hemi blocks coming out of Bill Mitchell Products (BMP Racing) in Edgewater, Florida. Whether you’re Mike Finnegan lifting the wheels on his blown 572 Hemi ’55 Chevy “Blasphemi” or a custom builder assembling a one-of-none custom street machine, BMP Racing has the block to fit your ultimate elephant build.

But what about those without hemispherical cylinder heads? Don’t they get any love? Of course, they do! Bill Mitchell Products’ radical 440 Wedge block is made from the same space-age 357T6 aluminum used for the Hemi engine block, ensuring it’s super lightweight while remaining incredibly strong. Each of BMP Racing’s 440 Wedge Blocks come with a 10.720-inch deck height, a standard camshaft location, .904″ lifters and includes screw-in freeze plugs and cam plug, all dowel pins and pipe plugs

The big difference is the options in bore sizes: BMP offers their aluminum wedge blocks with either a 4.240-inch or 4.490-inch bore. These allow for .010-inch in final machining, ideal for any big bore, big displacement wedge build. Each blocks 142-pounds, saving considerable weight off of the front of your race car or street machine. Equally each block retails for $5,895.75 and can be purchased via PayPal, Venmo or placing an order the old fashioned way.
