Best Kept Secret in the Big Block Mopar World

Just remember the nominal ID of the sleeve is just that. Most sleeves come .030-.040 under nominal bore size so you have something to bore to size (for honing of course).

The bigger the ID you start with the thicker the sleeve will be when you are done. I used to have a chart with all the sleeve sizes on it. That went away when the dyno went away. But I would look for whatever bore size I wanted and the length and I would get that rather than looking up a sleeve in the catalog.
Yeah, I was hoping a Ford 460 would work but I'll have to recheck the cylinder length.
I suppose what I'm looking to do is have 4.375 be the standard bore or a 4.400
