The block that took the industry by storm, by allowing you to mate the latest in LS1/7 cylinder heads to the traditional small block Chevy, the MOTOWN LS, has been built into a 427 cubic inch street engine!
Starting with World Products' MOTOWN LS block, topped off with WARHAWK 15° LS1 aluminum heads, a hydraulic roller cam and forged internals, expect well over 600 (though we conservatively rated it at 600, we've seen as much as 650, and with CNC porting, and amazing 690!) dyno-proven horsepower out of this combination, running on pump gas no less!
And remember, we build engines with lots of room left for durability and reliable driving - not near the extreme edge where breakdowns can occur, like many of our competitors! Compare us apples to apples and you'll find that only we give you REAL WORLD PERFORMANCE!
