So many motors for sale, so many deceptive ads. I see ads that state this is a GTO motor in the title and in the description it says it's from a big car, numbers say it's from a big car. All the stories seem to be the same and the word "Rare" is a word derived only by sellers. A factory 1969 426 Hemi is "rare," a Chevy ZL/1 all aluminum 427 is "rare." GM made millions of 455s. Not just a few million in cars, but in mobile homes, trucks and boats. They sit in woods, in fields, in garages and the back of garages everywhere. We know this, sellers know it they just want to believe everyone is a dumb-ass. I'm wondering if it's just better to buy the block and heads from machine shops that hoard their favorite brand motors and just let them make some more money honing, decking and assembling that way you have a bit more insurance you're getting something that's right.
