Weiand X-celerator mainfold.
I was looking on JEgs, and I saw a Weiand Single plane manifold X-celerator. The operating range is from 1500-6000 rpm. I'm trying to decide from this or the edelbrock RPM air-gap. What would be the chances of good low end torque with this intake.

Single plane 350 on the STREET isn't the best idea. You will lose bottem in torque, no way around it. If it was 50% track/50% street I'd say go for it, but you'll lose throttle response with it on the street. A single plane big block suffers the same fate, but not as extreme because of the massive cubes. I'd run a high flow dual plane myself, because that intake won't come alive until after 3K rpms.

oh. Alright. It says 1500-6000 i figured the low end would still be good.
:cheers:

I was looking in my How To Build Max HP out of your sbc on a budget and the Weiand Street ram was said to give just as good low end as a dual plane, but the high end of a single plan. I thought this manifold was along the same lines as the street ram.

I have one of those manifolds actually, but cant fit it under my hood right this moment. Make sure you take some measurements before you order it if you go with that one. It might fit on yours though cause I have a nitrous plate on mine.

I used one of those for ten years on 355 ci. Or should I say the model you pictured is one that has a removable center divider. The without div. was 2500-6500. But they run above 7000. They are one of the lowest plenum volume singles on the market.
The way I always looked at the low end TQ argument was. how often do you really drive below 2000 rpm. Going down the freeway I'm at 3000 rpm.

Exactly. Maybe we have not emphasized a matched setup enough on this forum. You need to get the car running nicely (dialed in) & then decide if you want to give up TQ or low rpm HP. Then what are you giving it up for since the cam is done by 5600! Do you have the 3.70 gears now? If they were in then, you would have less to lose.
... The cam is dead by 5600.
