Depends on a few things... The intake by itself is not the big horsepower maker, but must be selected to match, performance wise, the heads and valve train used and the application of the engine and the car it's installed in..... No one intake is going to be the best for all combinations.... We've used Victors and Super Victors on the BBF's for years.... They come ready for porting IMO, never have seen anyone pull an intake out of the box and run it in a competition type environment and realize the full potential of the intake......
