1973-74 455SD engines used the same lobe profile and timing as the 744 grind.
Was planned for the 041 cam but did not pass emission test.

I thought (going off memory) that the original intended SD455 cam profile was the 744, but that failed emission, and it was downgraded to the 068.
Thank you for the correction.
