I am in error. The distributor should get ported vacuum. The HEI should plug into the same place as the original distributor.

Today I had pulled the hose off of the carburetor and only had vacuum when the throttle open.

Sorry for the misinformation.

Today I also check my engine timing, is set to 5° BUDC.
