weiand intake

[Damein17]

just curious what gain a weiand for a 4 bb has over the stock intake for the 289/302

I can't tell you a firm HP figure, but both the Stealth and Action Plus will out do a stock intake. The Action Plus is very similar to the factory A321, C9OX, Cobra high rise, and Edelbrock F4B, but has the runners reversed. The Stealth is just about a dead ringer for a Performer RPM.

The Stealth and Performer RPM run head to head in the market place. I think the Stealth is over looked far too often for how well it works. I think it works a bit better than the RPM and it's cheaper by a substantial ammount.

In a nut shell instead of running out of pep around 5k you will run out of pep around 6k...assuming your other valve train components can support the extra RPM (like the cam is designed for power to 6k, the springs don't float at 5500, your carb flows enough CFM, etc.....)
