383Man, for your 3700lb combo, I would stick with the Street Dominator already on your motor.
Your nicely working engine, converter, and rear gear combo is effective, albeit pretty mild.
As such, I don't think you would benefit from the Victor intake at all.
- The SD intake does a great job as you already know.
Port the SD for even more gains.- The Victor intake sure looks cool. Save that intake for the stroker you are planning...
-
Not exactly what you are asking, but it is possible that the RPM intake could accelerate the car slightly better.
For some interesting comparisons regarding intake selection on a mild 440, take a look at two separate tests that Dulcich did on the
same engine at the same dyno facility (westech).
Yes, it is dyno racing, but it is reasonable test comparison data.One test session was to show the tuning process. (RPM intake)
The other test article was to show the difference between out of the box RPM heads and MCH-CNC RPM heads. (Victor Intake)

Check out the superior TQ numbers across the board with the RPM intake with this combination.
- The Stock RPM head/ RPM intake beats the stock RPM head/Victor intake combo at every point even in the un-optimized, baseline form.
- The Victor intake, MCH-CNC head equipped combo begins overtakes the tuned RPM intake combo at 5000+rpm, and even then, it is only by relatively small margins.

*1 7/8 headers in the RPM test, 2-2 1/8 headers for victor test probably skews results a bit...*
