The ARP catalog does not list a main stud kit for the 3.8.
Is there another block that has the same size main bolts as us that we can use? 351W? Are our main bolts metric?
I know they exist cause Coy Miller sells them and Tom Morana sells them. ?
By the way, there's a guy in Plymouth Michigan at a place called Flow-Tech who will flow your heads for $75. He's got a 3.8 bore cylinder so it will be correct. E-mail me if your interested.
