Engines are considered the "heart" of a vehicle. With that beingsaid, engines are built and assembled with accuracy. With over 10 years ofimport drag racing history and over 5 years of in-house engine building, weknow what it takes to build a reliable motor for the street and track. 

 Our experience has come from years of our own racing, research, anddevelopment. We know what it takes to build a race engine, and that knowledgeis put to any motor we build.

 

In-house Machine Work 

All machine work on the short blocks are done in-house."Allenbuilt" signature engines are personally built by Jeremy Allenhimself using the state of the art Rottler F-67A 3-Axis CNC machine.

  


Race Ready Internals 

Our customers receive the same quality parts we use in our own raceengines. AEBS sleeves are used because of their well designed sleeves. Thesesleeves are created from high quality ductile iron and are machined withprecision to insure a perfect fit. AEBS's closed deck design providesbullet-proof strength in our race engines, therefore it is more than adequatein any street motor. Although we recomend AEBS closed deck sleeves, we are alsoable to provide open deck style sleeves.

 

The advantages of building our motors in-house, we have the ability tobuild your custom motor exactly to the specs requested. CP Pistons are used inour race engines as well as our customers motors. The pistons are designed andmachined to Jeremy's custom specs. His custom design of the piston for thef20c/f22c blocks will resolve a specific problem other builders do not know about.

  


Pre-Assembly

 After the sleeves are pressed into the block, it is now ready to be honed.Jeremy has created his own techniques and steps to hone his blocks. The sleevesare honed in a specific cross hatch pattern to insure that the rings will sealcorrectly. A special technique is used by Jeremy to insure that the sleeves donot go out of round during the process.



Precision

Building an engine requires meticulous measurements and pinpointprecision. Jeremy builds our customers' engines with the same precision andaccuracy as he does with our own race engines. He cc's the domes, a method usedto measure and insure the correct compression requested in a custom engine,which not many builders do anymore. Every engine built is fully balanced,assembled, and blueprinted by Jeremy. All specs are confidentially filed away,but are available to the owner of the engine upon request. 



Product

In the end, after all said is done, you will receive a fully built andbalanced short block ready for install. Short blocks are sleeved, assembled,and finished within 3-4 weeks. If custom compression pistons are required thatare not stocked, please allow an additional 4 weeks for the custom pistonorder.
