I've heard that with 1.7 roller rockers having a '87-'88 camshaft is the best combination (i've heard those have the biggest profiles, but i may be wrong....don't have specs in front of me). I've heard that the cam that comes on the cobra is less aggressive than comparative years cam wise, but with the roller rockers they were more aggressive. In other words, using a non-cobra camshaft with the cobra ratio roller rockers would yield more of a power gain. I've heard that the cobra camshaft was about the same as the ones put in the MN-12 thunderbirds (during the one or two years that there was 5.0's in the newer T-birds) to provide more low end torque and as such the Cobra camshaft is occasionally called the "thunderbird" cam.
Can anyone verify/elaborate on this?
