DRR Elite
| Nothing better on a BBC than the Edelbrock Victor Jr. and it was only marginally better than the Edelbrock RPM Air Gap dual plane at 700+ HP. I’ve tested them all over the past 3 decades and currently make over 1000HP with the Vic Jr. on the engine in my Firebird. |

I am gonna agree with Ed on his response, with decades of running both of those pieces on many engines, and a few other variations, (including the quite good Torker 2-0 and the very disappointing "Performer" turd, (NOT the RPM version). I will also toss in my $.02 that will say "depending on your converter, gear, & launch RPM". There was some fairly extensive testing done by Hot Rod or Car Craft about 10 years ago (maybe longer). Their results could pretty much be summed up by Ed's advice. And I would venture a guess that Edelbrock easily spent more time and money than any other company in design, development, testing and refinement of 4150 manifolds for BBC's. Heck, maybe more than all the others combined. As for the magazine testing, the tipping point between which was better, the RPM Air Gap or the Vic Jr was RPM range, IIRC it was right around 5,500 or 6,000 RPM. If your requirement (application) was spending more time below that point, (as in a street car, street-strip, or very mild combo), the RPM was a more effective intake. If your car was a dedicated drag race machine, with a converter stall, matching cam and gearing that put the engine at or above 5,000 RPM for essentially the entire run, then the Vic Jr was the hands-down winner.
