Product Description

This is our 436 cubic inch All Aluminum Small Block LS Engine.  It makes an incredible 865 HP and 620 Ft/Lbs of torque.  Big Power and weighing only 405lbs makes a Winning Combination!


NOTE: Tests were performed with NON-OXYGENATED fuel. The use of OXYGENATED fuels (Example: VP113 or Q16) may produce a power increase, but will require a tuning change, including increase in jet size, for optimum performance.
