What's the difference in weight between a 6.0L iron and a 5.3L iron block? Anything? Thanks

 

~90lbs is what they advertise.

 

Alright, thanks

 

The 6.0 and the 5.3 iron blocks weigh the same. 90lb difference is between the aluminum and iron block.

 

My bad, I totally misread the question. I thought that's what he was asking doh

 

6.0 is a 5.3 with a 4.000" bore

 

So really the 5.3 might weigh more...

 

Heh, I thought they where the same block, but didn't know if anything was added for strength or what not..

 

No they are definitely not the same block. The 4.8 and 5.3 are the same though. The 6.0 has a larger 4.00 in. bore. Maybe you were thinking of the 5.3 which can be bored out to 4.903 in. to make it a 5.7, the same as an LS1.
