I realize that it will never be "numbers matching", the original engine has probably long ago been melted down and turned into a bunch of toyotas. But i always thought that originality counted for something?? I'm not ready to sell the car yet and i do enjoy driving it, but i'm looking ahead at a retirement project, and by the numbers a 326HO is more rare than a 400 so should be more valuable down the road. Let me have all your thoughts. Phil.
