Been trying to figure this out so I thought I would just ask here. Thanks guys!

 

I should get some big Camaro reference book, but here's what I know about big block Camaros. In 1969 some 61 or so received aluminum ZL 1's
427 ci. For 1970 the big block option was the 396 ( really a 402 ) . 1971
a few 402's. Yenko produced some 454's in the 70's, probably some other
dealerships too. I don't think Chevrolet put a 454 in a Camaro.
Don't let it stop you, though.

 

1970 was the only production year the Camaro got a 454.

 

They were just getting into the bigger big blocks into the camaro and firebird when the emissions thing hit them hard. Firebirds were the only cars coming out with 400+ cubes in the mid 70s.

 

Pretty sure the answer is never. There may have been dealer converted Camaros (like the Berger), but AFAIK, none rolled from the factory with a 454.

 

What about the copo's ?

 

The COPOs are the only Camaros that would have received a 454. I know no Camaro before 1970 got one, but I don't know any years other than 70 that did.

Nope. Corvettes had the 454 from 70-74. The full-sized Impala's got it all the way until 76. And don't forget the Chevelles had them too, especially the rare 70 Chevelle SS.

 

AFAIK, they were not available as even a COPO in an f-body.

 

I meant mid-late 70s.

 

454 was never factory installed in Camaros. You could buy them from dealerships like Baldwin-Motion with the 454 installed, but they were swaps. Only engines larger than 402s factory installed in Camaros were the COPO 427s.

 

X2 what angel71rs said. Baldwin-Motion installed them in brand new Camaros in the early 70's ~ They sold them as Phase I, II, or III depending upon the build up ~ they were some wicked street machines for the day
