<div dir="ltr">I went with a Moldex "ghost main" style crank last year and had to do a small bit of block relief as well. It wasn't unexpected since this style crank doesn't have the same profile as a stock crankshaft. I was working with a "new" block anyway so I had the machine shop do a test fitting before full prep and it really wasn't a big issue.<div><br></div><div>mike h</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, May 1, 2020 at 6:36 AM yellow04 via Fot <<a href="mailto:fot@autox.team.net">fot@autox.team.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">FWIW, the Moldex crank I bought back back in the early 2000's has <br>
counterweights that foul the webbing in the block as well. I talked to <br>
Ken Gilanders about it, he said that is what you want, use an angle <br>
grinder to make notches in the block for clearance. I think you need to <br>
grind two, maybe three webs.<br>
<br>
It is much easier if you remember to do that before you take the block <br>
to the machine shop and get it cleaned!<br>
