I am building an LQ4 for my suburban, replacing the 5.3
I have a new stock ring set and am wondering what grit hone to use. Had someone tell me the factory doesn't recommend the dealers hone at all if they freshen an engine. That sounds odd, but I am not used to these low tension rings.


Thanks in advance for the help.

 

Nobody gonna offer any advice?

 

320 or 400 is what I came up with searching on ls1tech. I went with 320.

 

Thanks! I'll do it! Searching on here was not very productive.

Thanks, the whole don't need to hone didn't sound right, but that is why I asked. Glad the world is still turning! Now lets get this sucker put together!

 

I wouldn't hone it yourself unless you have the real tools. Otherwise go to a machine shop. Wouldn't hurt to get it magnafluxed anyways.
