Speaking of main caps I bought a block that turned out to not have the orig=

=80=99ve been unable to find a machine shop that can machine them so there=
=E2=80=99s a round hole for the crank. The shop I had do my last block (and=
they do 427 race engines among others and are well respected) told me that=
the result would be ovaled out holes (not round) which obviously is not go=
od.Certainly there=E2=80=99s a way to make this work but I haven=E2=80=99t =
found it. I checked out another block shop but said they subcontract line-b=
oring to the the shop that said they couldn=E2=80=99t do it.=C2=A0
Has anyone else encountered this problem? I=E2=80=99ve heard that steel mai=
ns might be an answer but they=E2=80=99d still have to be line-bored to mak=
e them match. I hate to ship a block to get this done before I have reassur=
ances that they can make it work but does anyone know of that has successfu=
lly made main caps match the block? Given I=E2=80=99m spending a lot of tim=
e these days staying home and catching up on car projects in the shop I fig=
ured it would be a good time to start building the next engine.
Solutions or recommendations?
