Yes I’m looking at the BRC girdle. My block is already line bored with billet caps so I think it will need at least a hone. Idt it will be a bolt in. Kim
It's BCR:poke::D
That's correct, or to be clear, (check with BCR) I am pretty sure there is some machining involved, and please check with BCR, but I think this is all you need?? From their girdle description:
"The caps will sit about .030 above the pan rail surface so that the final fitment is to surface grind the caps to the rail. Basically the machine shop will just kiss the pan rail so that there are no issues with the front cover."
You may also have to extend the oil pickup a bit, per their description.
Line boring with the caps installed? IDK, it would seem like that is needed, but hey! check with BCR lol.
