Now that I have my bearings together on everything and took a good look at the old cylinders I have come up with some options. First, I am going to have the machinist look at the cylinder and see if he thinks it can be bored to fit a 64.75 mm piston. Only one of the cylinders was hurt so I know the other can be bored with no issues. These are factory cylinders so I believe the cylinders were cast around the sleeves which would have to be bored out to resleeve. If it needs to be resleeved I will be deciding whether or not to find a used cylinder and purchasing new 64 mm pistons and going back to a stock set up or what the price difference will be to resleeve it and stick with the 64.75 mm pistons that he sent with it. Like I said earlier, my experience has been with old muscle cars and this is something new to me. I am not worried about super performance and what I've gathered from everyone is there won't be any noticeable change from the factory 64 mm to the 64.75 mm pistons. I need to have a fairly cheap build but not risking any quality in the process. I will be running the cylinders over early next week for him to look at so I will know more then. What would anyone else suggest? Does anyone know of someone with stock cylinders in the Cincinnati, Ohio area that would be able to be bored to a 64.75 mm piston? Thanks for all of your ideas and suggestions.

What specs should I give the machine shop to bore the cylinders? If I use the 64.75 mm pistons what would the bore be and what would the bore be for the sleeves?

So the factory pistons were 64 mm? I understand all the machining and boring, I've built enough engines. I just wasn't sure if for some reason the dimensions for these were somehow listed differently. As my piston box clearly says 65.75 mm and the rings have 64.75 mm on them. Maybe it is a misprint on their part, who knows? So, from the advice I've gotten so far I will weigh out all the options and see what is the most feasible and economical. I know he spent a lot of money on the pistons and two sets of rings but if I can go back to 64's or the factory size and not be into it for a lot more money than I will. I don't really like cutting into the cylinders unless it is an only option but since I already have new pistons and rings I will see what the cost difference is.

I will check into a used cylinder. That hadn't crossed my mind but the cheaper I can build this the better. I only need one since it is gouged fairly deep. I am assuming there is enough meat to bore the stock cylinders to 65.75 without any issues? I am at work right now but I am positive the piston box had 65.75 on it and the rings had 64.75 on them. I will ask the guy I bought it from and see if he bought them as a kit or if he bought them separate. I'm pretty sure he bought everything from Cycle Specialties in Fairfield, Ohio.

I am having a friend do the machine work so the price won't be an issue. Even if I bought used cylinders than I would have that cost in addition to the machine work since I already have a brand new set of pistons and rings. Are LA Sleeve the best ones to buy or did you just use them as an example? Right now I only have $400 in it and still have some extras to sell that he threw in when I bought it. I still have a brush guard for a 3/4 ton Chevy/GMC to sell if you're interested, lol. I figure when I've sold everything else I will have basically gotten the Banshee for $200 plus whatever I have in the machine work and sleeves. I just want someone's expert opinion on which sleeves to buy and you already answered my question about the pistons and rings.

The piston box actually says 65.75 on it so I was just curious if they were measured differently. The previous owner had a local shop look at the heads and was told that it would definitely need to be resleeved. The gouge was a bit too deep even for the oversized piston. So the sleeves I should get are all one size and I won't need to look for any particular size for these pistons?

I am new to this forum so I would appreciate any help anyone has to offer. I am currently rebuilding my first Banshee, it is a 1996. The previous owner broke a piston skirt off and scored the cylinder wall pretty bad but is still within resleeving range. He had already bought the pistons and rings and they are as follows: Wiseco 513M06475 Pistons 65.75 mm and Wiseco 2549CD Rings 64.75mm. My first question is the fact that they are different sizes. Are they compatible and are they just measured differently since the rings are obviously smaller than the pistons? I am usually working on my Chevelles and rings and pistons are generally listed as the same diameter but are these normally listed differently? Also, what size sleeves should I be looking for? The heads are stock and will need to be bored to accomodate the new pistons. I am simply looking for the sleeve size that I need and are the rings and pistons that he gave me going to work together? I appreciate any and all replies and if anyone needs more info, just let me know. Thanks
