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.

Rebuild the 455 to 1970 specs. The grins from unleashing the torque(510 ft lbs. in 1970) will be worth it.

Yeah, what Bob said.
I concur. AFAIK the blocks are pretty much the same externally so the swap shouldn't be that hard.

Blocks are taller and wider but still pose no problems. Heads will interchange but intakes will not. He'll need to upgrade to a TH400 tranny to cope with all that extra torque.
