<div>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’ve been unable to find a machine shop that can machine them so there’s 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.
<div class="yiv2147745027">Certainly there’s a way to make this work but I haven’t found it. I checked out another block shop but said they subcontract line-boring to the the shop that said they couldn’t do it. </div>

<div class="yiv2147745027">Has anyone else encountered this problem? I’ve heard that steel mains might be an answer but they’d 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’m 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.</div>

<div class="yiv2147745027">In typically rookie race engine builder mode with the block I selected for rebuild, I pulled the main bearing caps (with my new fancy DeWalt 20V Impact Wrench) and then couldn't remember which way around they went. </div>
