Is it a stock bore / stroke 351w? What heads do you have? What are your HP & TQ figures?

The Vic jr. is designed to make power from 3500-7500, and the RPM and RPM Air Gap are in the 1500-6500 range.
If you have a stock 351w with stock heads, then I would say RPM or RPM air gap. Unless you have a pretty strong 351w or a stroker (392, 408, 418, etc) with good flowing heads, then you probably aren't making enough power in the higher rpm range to make good use of a Vic jr intake.

Just my humble opinion.....
