Re: Decal Replacement/77 Chevy Sport?

As far as I know the 454 would have been available on a 77 Sport;most options other than mandatory Scottsdale and restricted colors were available on the Sports and the 454 was available in the 1/2 ton until 79.

I have seen a factory 454 Sport in a 1976 and I have a 78 factory 454 Sport.

But the only way to be sure is to have an SPID from a 77 Sport with a 454.

Various options would be put on hold...sometimes just at one plant....if there was a supplier issue or more demand than forecast
