Hi,

Any one could clarify me the exact difference between short & long block?.

I can't understand yet, because in my country only the term "block" is used for the main engine part with the cylinder holes.

Then, for me a "short block" is a block with 2 to 6 cylinders, and a "long block" could be a block more longer: from 8 to 12 or more cylinders.


Thanks,


Denis V.

 

It's a matter of what all is assembled onto the "block".

Block = big casting with cylinders in it

Short block = block, plus crankshaft, rods, pistons, bearings, rings, assembled

Long block = short block, plus heads, plus usually cam, timing parts, lifters, valve train, assembled; may or may not include tin; no hard-and-fast definition for exactly what is and is not included, beyond heads

Not a question of "length"

 

best answer!!!!!!!!!!!!!!!

 

sofakingdom is right.

 

Oohh, very clear. Thanks


This is because english language is more efficient and short than spanish.

In spanish you must says every word. For instance, if I need buy a short block, I must ask in the store: Do you have a block with cranckshaft, pistons, rings, etc, etc?

Seller will reply (I know): Oh, no, we only have the cranckshaft.

Then, I'll go to the second store and the same question again: Do you have a block with...etc, etc?. Then, the seller will say: Oh, no, we only deal with pistons.

It will be a long history for a short block. Never says about buying a long block here.

Finally problem will be solved with a block imported from USA (very easy. With the free trade agreement Chile/USA items pay 0% import tax).


For this reason, I must know what a short or long block exactly is.


Thanks very much again,
