All the 66's should have had an SCV. What would be different between the MT and AT is the AT cars had what looked like a second accelerator pump on the other side of the float bowl. It is basically a a shock absorber to keep the throttle from slamming shut too fast. It should not hurt anything on a manual car. SCV or no scv depends on what dizzy you are running. If you are running an original 66 load o dizzy you need the SCV port. If you are running any later (68+?) dizzy you dont need it so it wont matter.
