Well,thanks for replies.I don't want to bore it cause I know where that will lead.....if your going that far you might as well line bore and turn crank etc. its just a 318 for a plow truck using up some parts to make a better than junkyard engine.Mancini has rings they didn't have cam I wanted so Jegs got my business, but they didn't have rings...so northen will be sending out rings. Guess I will go with cast. Will break in be the same with cast? Wish I had a local machine shop that would hone for me. Newbe to the hone ridge cuttting world. Thanks,Nate
