Recently bought a 1967 Cutlass Supreme was told it had a 1969 Toro 455. Some of you know this story and were nice enough to help me decipher the information. It turns out it is a 1967 425 Toro engine with the right heads and certain drill spot, looks to be original but haven't determined the insides yet. I never planned on keeping the car just finishing up some things on it, driving it and selling. Is this engine something so special that you would keep the engine no matter what or is it desirable but no big deal sell it with the car. Just interested in what you would do.
