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

Our experience has come from years of our own racing, research, and development. We know what it takes to build a race engine, and that knowledge is 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 Allen himself using the state of the art Rottler F-67A 3-Axix CNC machine.


Race Ready Internals
Our customers receive the same quality parts we use in our own race engines. AEBS sleeves are used because of their well designed sleeves. These sleeves are created from high quality ductile iron and are machined with precision to insure a perfect fit. AEBS's closed deck design provides bullet-proof strength in our race engines, therefore it is more than adequate in any street motor. Although we recomend AEBS closed deck sleeves, we are also able to provide open deck style sleeves.

The advantages of building our motors in-house, we have the ability to build your custom motor exactly to the specs requested. CP Pistons are used in our race engines as well as our customers motors. The pistons are designed and machined to Jeremy's custom specs. His custom design of the piston for the f20c/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 sleeves are honed in a specific cross hatch pattern to insure that the rings will seal correctly. A special technique is used by Jeremy to insure that the sleeves do not go out of round during the process.


Precision
Building an engine requires meticulous measurements and pinpoint precision. Jeremy builds our customers' engines with the same precision and accuracy as he does with our own race engines. He cc's the domes, a method used to 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 and balanced short block ready for install. Short blocks are sleeved, assembled, and finished within 3-4 weeks. If custom compression pistons are required that are not stocked, please allow an additional 4 weeks for the custom piston order.
