But where is this info coming from? Where, besides internet chatter. I've never seen it in print anywhere. Some type of reasonably bonafide proof. If both blocks start out new with the same wall thickness before factory machining and the 6.1 gets bored an additional .020 or .030 (I forget what the number is) more than a 5.7, then I guess the 6.1 would net out with thinner walls. Where is this information in print though?

For that matter, I think my Chrysler literature recommends not boring EITHER of these blocks more than .020 . I took this as they both have about the same wall thickness with their factory bores. I'm happy to be convinced otherwise with the right proof.

pic a builder and call them and ask. its old information man. pwr aka andy is one who swore by it. another builder name frank also claimed the same and posted results somewhere but i dont know where or remember. if it was internet chatter and no proof of it. you would not be getting me to state this claim. if i have not gotte this info from actual builders you would not be seeing me with a 5.7 block in my build. when a new 6.1 is only a 1000 bucks new from mopar. it would be insanity to not run a bigger bore unless it has issues. those issues are the cylinders are not ductile iron but cast and the thinner they get the weaker they will be.
