Hi skunk,

Thanks for posting the cam chart and info. It's interesting. I didn't know that Ford changed the cam in their 5.0 Mustangs between the 1988 and 1989 model years. My car, which was built in June 1988, just missed the cut-off date of August 1988. This change resulted in a loss of 3 horsepower. I think that was also the year that Ford switched from speed density to mass air, which also caused the Mustang to lose horsepower.

Augie, in '88 all California 5.0's got the mass air set up. In '89 and afterwards, all 5.0's across the board got mass air.

The cam profile change resulted in a 3fwhp lost like you stated. Mass air had no effect on hp rating. There was a corporate hp rating drop later '93^ due to change in testing/revised output ratings.
