I'm looking for advice to the best inline quad carb intake for my 505 Hemi with the Indy 426-1R legend heads.

The engine will see 7000rpm with a solid roller 263/269 @ .050" Camshaft. I'm planning on using two Edelbrock AVS 2 800cfm carburetors.

The intake alternatives that I'm currently looking at are: Edelbrock Performer RPM Dual quad (#7524). INDY Mod Man intake and the Stage V 2-4BBL manifold (not available at the moment from Tim@FHO)

Please let me know what you guys think.

I haven't used them, but from what I've seen, the Stage V inline manifold would be my choice.

Unfortunately not available at the moment. Tim@FHO said he was focusing on ramping up the production of Stage V heads before he gets on to the intakes.

If you want a Stage V you'll have to find one, I'm sure it will be awhile before he gets around to making those if ever. There is some of the old KB knock offs around on ebay sometimes. The great thing about the Edelbrock is it checks all the boxes. Street Hemi height and spacing for carbs and cold air systems. No other intake does that. EFI ready is available. Fuel rails etc is available. Takes Street Hemi air cleaner. Power, RPM's, fit, chrome dome, shaker hood, air grabber, complete EFI system available, it does it all. Wouldn't take me long to decide.

I looked at all three and with the best advice available went with the Stage V over the Edelbrock - currently I run the AVS2 800 CFM and with recent improvements its making just shy of 900HP - over the winter I will be switching to the new Edelbrock 4150 design 850's

The mod man has its place but with my experience on a Wedge with the modman - I really did not like the big open plenum and lack of runners

How soon do you need it?

If "pretty soon" is the answer then I'd probably get the edelbrock, it shows in stock RN.

The main thing I like about the Stage V is I like Holley carbs

I wouldn't use the indy intake.

I use the Edelbrock but I think the Stage 5 would flow better even just due to runner angle.

For whatever reason the Edelbrock runners are flat and does not match intake port angle. I had to do a lot of porting to try and match it (not so much size but matching angle at the flange)

They pop up for sale every now and then. Gotta keep an eye out for one. Facebook marketplace.

The Stage V is a knockoff of the KB Marine intake manifold except in single plane. Mopar also repoped the KB intake. There is one of the Mopar repops on ebay. https://www.ebay.com/itm/156012103598? The seller claims it's an original but I'm sure you can figure that one out. The seller doesn't accept returns if that tells you anything.

You can decide if this is relevant or not to your situation, but I will relate my intake experience:

My Hemi is a 540, similar cam specs to yours with MCH ported Eddy heads. The biggest difference is that I went with a single 4500. I talked to the guys at Indy Cylinder Heads as to which intake would be best for this primarily street driven combo. Coming from wedges, I assumed they would surely recommend a single plane for this engine which peaks at 6,800. But nope, they recommended the dual plane.

Being suspicious, I actually bought both and when I broke the engine in on the dyno, I tested both intakes back to back. SURPRISE to me! The dual plane only gave up a dozen ponies or so up top, but picked up 30+ lb ft of torque. Now the 540 really doesn't need much in the way of more torque, but I suspect the driveability is a bit better, too. But I haven't ran the open on the street to prove that.

Just my .

And it's more money, but you could just pick up the intake that is readily available and have it ported. Surely, that would bring even the second choice intake into competition with the best. At least I think it would.

I'm not really interested in trading but since you want a Stage V and since the theme of my test stand engine is Keith Black, I would swap you for a perfect KB Marine intake. When I asked how many he made he said he really didn't remember, but he thought it was 75. So they are out there. I've had more than one. I put the Stage V intake on my test stand new less than a year ago and it still looks new. You pay all the freight.

I have a couple of each manifold and both perform well with some work and port matching. However, my tunnel ram picked up way more horsepower over any of the other dual four combo's obviously by design.

Have you thought about a Tunnel Ram? The old Weiand is a great piece!

Are you asking for drag race only advice or ?
If drag race only all of them should work well with your parts,
If for street and strip use you may want to think about using a dual plane intake manifold instead for the better drivability under 5000 RPM

Thanks a lot guys for contribution to my gen II hemi intake quest. based on this information and the availability I'm leaning towards the Edelbrock intake.

I have 2 of the older Wieand tunnel rams for sale, if your interested. Jim.

Another option....Not sure why nobody suggested it. Plenum is adjustable.

I got an older nicely ported Weiand tunnel ram on the engine now but I want to keep everything underneath the hood.

My Indy tunnel ram does stick through the hood. I just made the scoop to accommodate the tunnel ram.

The Stage V is a little taller than a factory manifold but still fits under the hood on my Cuda The shaker sits up a little higher out of the hood than factory. I have a marine manifolds also. The nice thing is it has the same carb spacing as the stage V so the same shaker base works with either.

One of the intakes looks just like the one you have, the other, also a Wieand, is roughly an inch shorter.
