We all know the #'s denoting a LS6 in our cars.(f-body)
# 12561168
What is the ID casting #'s for a LS1?? Are they the same for all LS1's.
(mine is a 2001)

The reason I'm asking is because that "engine number" is written on our registration card and I want to get another motor.
If I were to get a motor with different #'s than mine then it is a hassle to get it registered.

Any help appreciated.

ttt..

 

last three are 378 for LS1

 

Hmmm, the "engine number" on my registration says

112108569

 

that's an ID number not a casting number

 

So every LS1 has a different ID number right?

 

not sure

 

Where is the block # at?

 

driver's side of block just below head
