Turnkey Custom Built 460 Engines

Custom Built EFI 460 Engines with Roller Cam

From mild to monster, we can build an engine to meet your horsepower and torque goals.  Whether you are looking for a smooth daily driver to get you back and forth to work, or a fully built pavement peeler we are happy to get you set up with a big block to meet your needs.  What we call a standard build is well beyond any standard.  Each of our engines we build (in house) are held to the highest standards of excellence.  We went through 6 different machinists to find one that did work to our level of expectation.  The entire engine is completely machined and only premium quality parts are used.  There are no corners cut or sub-par parts that go into an engine coming from us.  We custom build our engines to suit your needs and give you optional upgrades to choose from. Against industry standards and unlike any other engine builder we take our process to the next level.  We actually install each motor and put at least 300 miles on them, yes miles on the road.  This ensures you are receiving an engine ready to drop in and drive.  Not a potential time-bomb of “God I hope this holds together”.  We have all seen too many engines come apart in the first week, or sometimes a month later.  No one can afford that lost time, money, and heartache.
