Description:

Borowski Race Engines, Inc. strives to build the best engines in the world. If you are interested in billet blocks, you need nothing but the best. To attain that goal, we need to work with the best suppliers. Energy Manufacturing Ltd. is a sister company to Callies Performance, our go-to for cranks and rods. Ben Mens explains in this video why Energy is the best choice for a billet aluminum block for your extreme LS, BBC or Ford build. 

First let's start with the raw material - 6061 aerospace grade aluminum-scandium alloy. Scandium alloys are used for extreme applications where lightweight, machineability, high strength and much improved heat resistance are needed - like Russian Mig 29 fighters and Smith & Wesson AirWeight 357 Magnum frames.  Energy both heat treats and cryogenically treats the billets to get them to their peak potential.

Next comes the design, which we love, and quality of machining.  Ben mentions chamfering as one of their items of focus.  The reason is that any sharp edge is a potential stress riser and point of failure. A perfectly chamfered block is much less likely to fail - all else being equal.  What we also really like are Energy's short lead times.

You heard Ben mention that we are now using an Energy billet aluminum block for a methanol twin-turbo LS build. True story! You'll be seeing that soon.  Here is a preview:
