Help me identify this car PLEASE- 1970

I just purchased a 1970 Rallye 350. All info I can Find says car is equiped with 350. Car has a 455, previous owner swears its all original. Have build codes from trunk lid but cant find access to decode. HELP!

maybe its a hurst, although it would probably have badges, i know in the late 60's and earily 70's they did put 455's in some of the cutlass' but i think mostly in hursts.

the rallye 350 was only produced with the 350. sorry to say but I think youve been dooped. the hurst that had been released came with a larger engine yes, but they also had al the badges and paint to prove it. plus they wouldn't use a rallye cause that was already supposed to be a performance vehicle. Is the car atleast in nice shape? there are also a lot of 442 registries that could probably help you with the vin, and body trim tag and engine codes

Thanks for everyones help. Codes and build sheet indicate this car was built with a 455. It is very rare. There were less of these cars produced than the W31 car. It appears to be a dealer special order. Built in the Lansing plant.
