This is a balanced and blueprinted, dyno-tested combination that will produce at least 525+hp, 575+ ft-lbs of torque, run all day long on pump gas and is built to take a 125+hp shot of nitrous. Final displacement is 437.7 cid. Engine is new on the stand - never fired. I kept all of the UPC codes and install documentation for the new parts, which is pretty much everything other than the block, crank and intake manifold.
It’s got better parts, machine work and assembly detail than every other comparable 440/451 crate motor currently for sale for much less money. Period. It's pre-oiled and ready to install. Parts and machine work include:
