340-HP 3.6-Liter Four-Cylinder with an LS Head

The block is rugged and designed for high-torque continuous use in extreme environments. We then slightly altered the block to successfully mate with our Blueprint Engines LS head.” Blueprint brought the engine to see if there’s a market, and they were flooded with ideas from attendees, including swaps into S10 trucks, early Jeeps, circle track cars, and more.

f configured for a performance application, this bore and stroke combination could produce well over 300 horsepower and nearly 500 lb-ft of torque. The Blueprint Engines 3.6-liter will accept any standard GM bellhousing, so the swap possibilities are endless.
