When someone uses the term "long block" what does that mean? Example:

B16A Sir-II (Long Block). I was always curious as to what that means...Thanks in advance as always!

It generally means a complete engine (ie-block and head assembled and ready to run). There will be a few things that you transfer from your existing motor. By comparison a Short Block is an assembled block without the head or other external parts. When the term "crate" engine is used that means a ready to drop in and run motor; it has been on the dyno and is usually sealed-you supply only a few items that are bolt-ons.

 

I see. Thanks for the info. This doesn't usually include the tranny, does it?

No

That is generally called a complete changeover.
