My 422 smallblock build

Not scared at all, just don’t see the reason to use a manifold that is designed to produce power between 4000-8500when the majority of my driving will be between idle and 6500. Am I missing something here? If I planned to bracket race this car sure as **** I’d sell the dual plane and slam a Strip Dominator on it and hold it to the rug. I thought the dual plane would be perfect for my intended usage. Would a single plane make a few extra hp at max rpm? Almost definitely. Will the dual plane outperform from idle to 3500? I’m betting so.

Because the intended RPM doesn't mean a thing. They should NEVER put that junk in their catalogs.

Think about it. A Strip Dominator on a 273 would take a totally different cam and a significantly smaller carb when compared to a 340 or a 408 or it will be a pig. That's one reason why guys lose bottom and middle using a single plane. Way too big of a carb, and I don't mean CFM ratings. I mean Venturi diameter.

A dual plane can take way more carb than a single plane can before you lose bottom and middle end.

Cam timing is a HUGE factor in driveability and most guys use too LITTLE duration and way too wide a LSA and the intake manifold gets blamed.

I'll say it again, a GOOD single plane will beat the pants off the best dual plane every single time. But you have to stand your ground and not let cam grinders do crazy stuff. You have to buy a tuneable carb and work with it.

If you build it correctly, the single plane wins every single time.
