Not to take anything away from the Olds 455, as it is a very powerful engine with a lot of torque, but if it has had water in a cylinder, it will need a complete rebuild. Boring, new pistons, and possibly one rod, if it hydro locked. The 400, on the other hand, unless it's been rebuilt, has cast pistons and rods, and if you're going to build it for performance, at the least, the pistons need to be changed. Performance isn't cheap, anyway you look at it!
