Could someone please tell me if the tourque specs are the same on the aluminum LS6 block as they are on the LS1 cast iron block.

 

As there is no such thing as an iron LS1/LS6 block, this question is not answerable.

 

Lol and I believe you mean torque.

Here's a good site. Not sure if it'll help you though.

yes they are.

 

As previously stated, yes they should be the same. Only real difference between the two that I can think of off the top of my head is that the LS6 is said to have small "windows" at the base of the bores, which supposedly make the LS1 block the stronger one out of the two.
