Everyone point and laugh at the newbie, but here is my stupid question. Just dropped my 302 block off to have a block prep done to it (hone, freeze plug, install cam bearings, etc). The guy called me a minute ago and asked where my "main plates" were, and that I needed to drop them off so they can attach the engine and hone it. I gave them a bare bones stripped down block, what part are they asking me to bring back? I tore this thing down about a month ago and it has been sitting in my garage waiting to be cleaned and rebuilt. I know I have everything, just wondering where to start looking.

 

Nothing? Could they have meant main caps, like for my main bearing? Anyone ever worked a block prep at a shop that might be able to shed some light on what they need?

 

Sure they weren't looking for the main caps?

 

Would have to say main bearing caps. Depending on the amount of machine work being done, they may do a line bore/hone to "clean-up" or repair the main journals.
