Re: I'm finally starting the project
Welcome to Team Camaro, Ed - you will get pestered to post some pictures of your car!
To answer your question about overboring the block, it really depends on what condition it's in, and how worn it is - as it's a bare block now, you'll be able to check for wear and if in doubt, take it to a reputable machine shop and get them to check it for you. It may clean up with a hone, or it may require boring out. Did you mark the main caps according to their position before you pulled the engine apart?
