427ci Short Block "The Executioner"

 Allow us to introduce the Executioner! The latest release from our Brawler Engine Series. You'll be carrying out a death sentence to any of your opponents with this engine under your hood! This stroker engine starts out with a fresh Gen IV Aluminum 6.2 block. We then perform our re-sleeving process that drops in much thicker/stronger ductile iron sleeves allowing us to take the bore all the way out to 4.125". Lastly, we drop in our TSP forged rotating assembly, which is widely proven to ensure durability even under the most demanding conditions. Combined, you've got a solid recipe for light weight, power, and strength!

The goal of our Brawler Engine Series is to provide customers with high quality engine choices that are ready to ship out in a few days. The same parts, machining, care and workmanship goes into these builds as our custom engine program. All engines are balanced, blueprinted and assembled in house to exacting TSP tolerances.
