Mopar R1 block

too thin walls and you go slower and ring life goes away and you run hot
been there done that
let;s see what the sonic test shows
did you say whose pistons and cr?
how about a recap when your results come in
is this a siamese block?
chevy is siamese at 4.125 with a 4.40 bore spacing
It’s a over next winter project, that I will be prepping the block for soon.
I’ll probably deal with BPE as he is 45 minutes from me. Ohio crank is close also.
