A short block is basically the engine in it’s purest form, only the 5 engine plates and the front cover, with the front pulley hub/boss only. No oil pan, no flywheel, no water pump, etc. This is what all engine rebuilders sell, and nowhere can you buy a rebuild with everything included on the engine. IF you are shipping in a core, it is generally accepted/requested that it be in short block form.

A long block is the engine complete as it would be pulled from the car, with all manifolds, accessories, and wiring still intact (minus power steering and a/c).

 

Many people are not comfortable with removing and then reinstalling all the manifolds, wiring, etc. The rotary has a very complicated EFI/control system, and this is understandable. How well this phase of the install is completed is directly related to how easily/well the new engine starts and runs. For this reason, many people ask if I can do this phase as well. I gladly do so for an additional $150 service charge for 91 and prior engines, and $300 for 93+ engines.  This includes replacement stock vacuum hose (where necessary) etc. Please send the complete longblock engine if you choose to go that route, not a half stripped version. Note that shipping costs may increase 10-40% for a longblock due to added weight (375 vs 225).
