If that's true and you could come up with a 455 block local you could add the 425 steel crank, rods and pistons in a rebuild. Can anyone verify the 425 crank in a 455 block? John

This is true. My 455 block started it's life as a '65 or '66 425 block, whoever rebuilt it threw in 455 rods, pistons, crank, flexplate, and it has B cast heads. I find it somewhat curious that with the existing performance mods my engine has, that they chose to go with 425 heads instead of a set of 455 C heads or the aftermarket edelbrocks...perhaps they simply couldn't find anything better...Olds big block parts are hard to come by in this region.
