hey guys finally going to start my build i just recently got a 5.3 cast iron block i was wondering if someone had a spec sheet compared to the ls1 aluminum 5.7 block in other words will i be able to use an aftermarket ls1 5.7 rotating assembly in the 5.3 block, or is the stroke different? i know the block will need to be bored. just wondering if i can turn the 5.3 into a 5.7 thats all.

 

just answered my own question guys saw the post a few below this one. sorry for the jam up!
