Speaking of main caps I bought a block that turned out to not have the =
original main caps. The caps on there did not match up with the block =
but I=E2=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 good.
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-boring to the the shop that said they couldn=E2=80=99t do it.=20
Has anyone else encountered this problem? I=E2=80=99ve heard that steel =
mains might be an answer but they=E2=80=99d still have to be line-bored =
to make them match. I hate to ship a block to get this done before I =
have reassurances that they can make it work but does anyone know of =
that has successfully made main caps match the block? Given I=E2=80=99m =
spending a lot of time these days staying home and catching up on car =
projects in the shop I figured it would be a good time to start building =
the next engine.
Solutions or recommendations?
Thanks
Bud
