Short vs. Long Block

Hi all,

All the mechanics that I have talked to around here do not rebuild engines. Instead they said they replace them with rebuilt engines. I was wondering what the general consensus was. I have an I6 4.0 and it has been a great engine. What is the difference between a short block and a long block engine? What would be better? We do some 4x4 driving but nothing extreme and so long distance driving. But, mostly she an everyday driver to and from work.

Longblock = block + head
So you want a rebuilt longblock.

Warranty. If it's an aftermarket engine that advertises any type of performance increase see if you can get them to tell you what parts were used.
