Built in house, our series of performance short blocks are precisionly assembled and blueprinted. We utilize precision machining coupled with 3 step quiality control to ensure each short block assembly is within the specs it needs to be to fit it's application. From the street to the track, we are able to meet or exceed the same quality and performance as the bigger brands out there, without the hassle of cross border fees. 

 

Our R600 Street Series blocks are capable of handling up 500 whp (close to 600 BHP) with supporting modifications. 

 

Each block consists of the following

- New or seasoned case halves

- Vapor Honing cleaning (For seasoned case halves)*

- Precision Bore and honing process

- New OEM crankshaft

- King Bearing main and rod bearings 

- ZRP or Brian Crower Forged connecting rods

- ZRP or Wiseco Forged pistons w/ file fit piston rings

- New OEM Case Bolts 

 

Each block comes with break-in procedure, new oil weight and maintenece interval. 

 

*Vapor Honing is a process that utilizes a water and  blasting media mixture that allows cleaning of engine components to brand new appearance without the risk of burning or removing the actual block surface. This is especaially important when working with softer metals like aluminum. All case halves are degreased, bolted together and then have custom block off plates installed to ensure no slurry gets inside the oil galleys. The block is then cleaned out and cyclone cleaned to remove any excess material on the outside of the block. The result is an old block that looks like it just rolled off the assembly line.
