Engine Packages

We have partnered with World products/Erson cams/PBM to now bring engine packages at an affordable price. These packages are sold dynoed and ready to go. They are complete Dynoed from intake to pan. These packages are all machined and hand assembled in house just as the custom engine packages we have had such success with for over 20 years. Each engine comes with complete documentation just like all our custom engines. All clearances have been meticulously checked and documented and supplied with one of our KTRE spec sheets for each individual engine. Also included is a dyno and flow sheet from each specific engine, a rotating assembly balance sheet, all valve springs have been measured and recorded. As well as a complete build sheet reflecting all the individual parts included in each motor these are not generic specs or records, all clearances are checked and documented for every engine built. These engines utilize BMP or Profiler heads with many packages fully CNC'd ports and chambers, World products blocks, PBM or Callies 4340 forged crank and rods, top of the line PBM/Morel lifters and Erson or T and D rockers, Erson cams, Edelbrock intakes, Canton or Milidon oil systems, Melling oil pumps and pickups, MSD distributor and plug wires, ACL or KING bearings, SFI harmonic balancers, Cometic head gaskets, Felpro engine gaskets, Joe Gibbs oil, Wix oil filters.
