Yeah I remember that conversation but (and I even read it twice so as not to look like a tard) I was curious as far as max bore on these sleeves. I didn't see that info in that thread.

I'm looking in to doing a big bore/short stroke to get around 400 ci. I don't know if it's possible (I am a lil tarded) but I think this would be a good combo for me and would have a great rod ratio with unshrouded valves.
