Whats the difference? Which is better?

 

Short Block: An engine WITHOUT the heads.
Long Block: An engine WITH the heads.

 

short block- block with rototating assembly. Long block - engine block rotating assembly with heads. Short but to the point,heh heh, hope this helps.

Can't believe you guys didn't jump at the opportunity to make a joke over that question

 

More specifically, a shortblock assembly is the block, crankshaft, connecting rods, etc. that make up the "bottom end" of the engine. Longblock is basically a shortblock, with an intake, heads, etc. that make up the "upper end" of the engine. Obviously, a shortblock engine isn't complete, and therefore could not create power. So, to answer your question, I'd say you'd wanna be looking for a longblock, unless you plan to transplant your stock heads on a new shortblock...

 

You mean like this?

HEAD!!!
