Stock ls1 bore? I’m doing a ls swap on a 93 mustang coupe and about to purchase some pistons rings.
The engine was a 5.3 ls but is bored out to a 5.7 and is using stock ls1 pistons and rods.
What size piston rings should I get? I called one builder and he said a 3.898. Another one said 3.905. So I’m confused.

Thanks for the replies.
Im going to talk to the machine shop hopefully Monday. I got the ls1 rods and pistons out of my old ls1 and when I took them to the machine shop I forgot to ask what size I should get since he will bore the 5.3 out. Tried to call but apparently his wife was sick so he will be out for a few days.
I was going to try and get the rings to give to him first thing Monday morning but I guess I’ll wait to be sure it’s 3.898 size rings.
