5.3 overbore
Lets say I want to purchase a 5.3.
Lets say I want to bore it .120 and drop stock LS1 pistons in it.
Im told this can be done on a 5.3 iron block, can this be done to the 5.3 aluminum block as well, without installing new sleeves?
Thanks

Engine Masters had an article within the last 2-3 months were Tony Mamo built a 600+ (crank) hp 383, using a new 5.3L ALUMINUM block bored out to 3.898" with a 4" crank.
So yes, based on that info, I'd say it is very possible.

It was this buildup and Jason(I think) from Thunder Racing's 383 where I noticed something similar. I believe the sleeve has the same outer diameter and is either thicker or bored more for the 5.7L's
