What is it about late 60’s American iron that is all about massive? In a day of high gas prices and eco-friendly engines, excessively large motors are no longer being produced by Detroit. However, if you want the cast-iron excess of yesterday, then look no further than our Chevy 540 stroker long block motor.
The Proformance Unlimited 540 long block engine is definitely one of the biggest and baddest power plants that you could drop into your engine bay. Featuring an Eagle forged steel crankshaft, your choice of SRP or Mahle forged flat top pistons, and Dart aluminum cylinder heads, our Chevy 540 long block, pumping out 630 HP, demands to be noticed sitting between your shock towers. This is truly one awe inspiring crate engine.
From custom painted engine blocks to our exclusive March Performance serpentine belt system, Proformance Unlimited can supply you with the long block motor that you have dreamed of and others fear! With over 50 years of shop experience, you can rest assured that we are here to help design and build the engine combination that best suits your vehicles needs. Unlike our competition, we stand by our long block motors with a one year, unlimited mile warranty.
