I've been looking around at different LT1 block cause I plan on building a very "healthy" motor in the near future and I was wondering. What are the differences between a short block and a long block? Is it simple that the long block is actually longer then the short block?

 

the short block refers to everything below the heads....just a block and rotating assembly
long block refers to an entire motor....or at least up to the heads...

if you're looking to build a "healthy" motor, i'd find a good short block somewhere and buy a set of good heads (AFR, TFS, or call someone like lloyd elliot and have him port and polish a stock set)

 

IM guessing bigger bores?

 

I hope I am saying this right.
A short block is the block only with crank, pistons bearing and caps assembled only.

A long block is all of the above plus cam, heads and valvetrain plus timing set.

 

Short block means just your bottem end long block means everything but your bolt ons like intake and accesseys

 

OoOoOoOoOoooooooo ok. Thanks a bunch for clearing that up for me. lol why dont they just call them short blocks and tall blocks? cause when I think "long" I think length not height.

 

some people do...just a preference of syntax
