A friend of mine has a '71 Olds Cutlass convertible 442 clone and is planning on rebuilding the engine (350) in the next couple weeks and has the opportunity to buy a 455 out of a '74 Toronado. Either engine is going to need to be rebuilt so is there any reason not to put the 455 in? He's not worried about gas mileage because he only puts 2-3000 miles a year on the car. Since the car is a "fake 442" keeping the original engine isn't that big of a deal to him.
