Shafiroff Horsepower Dollars!

Just What Is Shafiroff Horsepower Dollars?

For a VERY LIMITED TIME, you will save $1 dollar for every horsepower advertised on ANY of our Realstreet, Ultrastreet, Big Dawg or Twisted Pump Gas Engines!

For example: If you are looking at one of our Small Blocks and you want a 434, the 595HP version will save you $595 dollars! Or if it's a Big Block and you want serious horsepower, our 632/1050HP would save you $1,050!

So pick your engine, Chevy or Ford and give us a call!
