Why spend the money on a CH-4B which is EXACTLY the same as your stock intake except that it's cast in aluminum?



From the Mopar Muscle magazine article comparing intakes:
Edelbrock CH4B:
This intake has been out of production for years but retains a loyal following. Once Edelbrock's premier two-plane intake, it also sold through Mopar's Direct Connection program back in the day and is well remembered by old-time Mopar enthusiasts. We borrowed this one from local Mopar bud Harry Gicesare. The CH4B is similar in look and layout to the stock intake, and is a relatively low profile design. The numbers showed a substantial improvement compared to the stocker over most of the range tested, particularly higher up in the range. Interestingly, peak horsepower occurred very high in the rpm range with the CH4B, equaled only by the new Victor. It tended to favor higher rpm performance and was kind of soft at the bottom of the range. The averages were quite good among the other two planes (Weiand Action + and Performer RPM), well ahead of the stocker. No wonder people remember this as a good intake.
