    Hello all,

    I just picked up a 78′ Cortez and the seller stated the engine is a olds 403 and not a 455. The coach looks to be factory. Does any one know have to tell the difference ie block stamping of something like that. I know GM changed production to the 403 around this period but did they make there way into the Cortez.
