This engine was purchased for my 93 coupe but I’m interested in the new 2011 5.0 motor from the Mustang GT instead – Read about that HERE. I’m offering this for $7000 - the original cost was $9000. I might also consider selling the engine without the intake manifold for less. I will use this engine before I give it away, so please no low-ball offers. If you’re into Mustangs, then you know what you are looking at. A 331 stroker engine with forged internals in an aftermarket Dart block. This engine was designed to support 800+ horsepower. This is completely assembled including the complete valvetrain (lifters, pushrods, rockers, timing chain, timing cover, water pump, oil pan – everything. This engine is 0 balanced – so keep that in mind – your flywheel must be capable of 0 balance as well. Oil pan has had a bung welded onto it for oil return from your supercharger or turbo system. Below are the specs for the engine, including the blueprinting specs.
