Looking for suggestions for an intake manifold for a 426" 2nd gen Hemi.
The catch is it needs to be a cast intake (sheet metal not allowed) and it needs to support 2x4's up to 8-8500 rpm.
What should I be looking for?
This is a race only application with a 4-speed for Nostalgia Super Stock.

If you are talking inline I assume the Stage V would be the one. I have used the Mod Man and it ran well but it has a bolt on sheet metal top. You would have to see if it's legal.

The top of the manifold can be fabricated.
1.16 INTAKE MANIFOLD INTAKE MANIFOLD: Sheet metal intake prohibited. Manifolds restricted to commercially available cast units. Top of manifold lid may be modified and fabricated as necessary to accommodate carburetor placement.

Got to love the wording. Does that mean yes or no? Depends on your relationship with the tech guy...

Good. Now we need someone (maybe AndyF) to chime in as to which of those 2 would make more power. I have not run the Stage V. I hate say anything good about Indy but I couldn't believe it when we took off a $3,500 Ray Barton intake and put on a Mod Man and only lost 3 hundreths.

Mmm, I like my Indy Tunnel Ram (of course name has all been welded up & bead lasted off) with dual Dominators. Spun up to 8100 on Dyno. It has a bolt on cast top (not sheet metal though).

I purchased a freshened up SS/AH short block that was set up to shift at 9500rpm. So the bottom end will live. We are not going to turn it that high so we can save the valve train LOL. I couldn't find any info for rpm ranges for most of the intakes I have looked at online. Even considered some of the old rat roasters, but there is even less info on those!
I wish I could run a tunnel ram, but they are prohibited. That leaves only a few choices. For the carbs, I plan on using the carbs from my wedge. They are heavily worked over Eddie 800's. Right now they are working well on my 496" wedge shifting at 7600 rpm.

If you can't run the Indy Tunnelram, then you're gonna want the Stage V inline dual quad manifold. Being that this is for NSS, Indy has the big box style crossram hemi manifold w/ a couple different tops available (twin 4500 or twin 4150). I'm not sure, but I'd bet the Stage V manifold would make more power than that Indy crossram manifold.
Here's the Indy crossram...

I'm running the Eddy single plane... It has stock carb spacing! I'm very pleased with it and the Victor Jr heads!

I would guess that the Rat Roaster is a dog compared to todays manifolds. I figure the Indy crossram is the same. The new Edelbrock is great for stock cars because you can still use the stock air grabber hood, but for your application, I'm betting on Stage V or Mod Man.

Thanks guys for all the suggestions.
With the RPM we will be running I would think the larger plenums of the Indy, or the old Rat Roaster would probably give an advantage over the intakes with smaller runners.
With my wedge I launch at 5700 and shift at 7600 (4-Speed)with a 4.86 gear. This past week I installed a 5.00 gear and we adjusted 4 link to tame the wheelies.
Idle is and street manners are very low priorities as this will be a high winding race only setup.
What are your thoughts on runner lengths and plenum volumes for these intakes? Does anyone have any links to flow data for the INDY or Stage V intakes? Stock and or modified?
We are allowed to use spacers to increase the volume of the plenum. On my wedge I am running s STR15 with a 1/2 plenum spacer and 1" carb spacers under the 800 cfm eddies. It seems to work well with this engine.

From everything I've seen, the old Rat Roasters don't come close in power to any of the newer manifolds. None of the old style crossrams do either, but they do look cool.

Very nice DoubleD. What kind of compression are you running, and what fuel are you using.

Compression is just at 13-1 with victor jr. heads - I will be running C-12 to be safe its in a 64 dodge NSS. its screaming for bigger carbs - I have a solution for that - but that will be down the road a little Nice piece. My 528" as pictured above made slightly more than that with only 10.5:1 on 93 pump gas since I still street drive all of my cars. Yep, I knew mine was going to want more for carbs which is why I went with the tunnel ram and two 1050's.

I hate say anything good about Indy but I couldn't believe it when we took off a $3,500 Ray Barton intake and put on a Mod Man and only lost 3 hundreths. Which Barton intake? I'm only asking because I'm running a modman and it works great for what I do but I figured one of his single planes would really wake my combo up. Had to be a crossram. The only thing the big Barton or Indy single 4500 intakes won't outrun is a good tunnelram.

RICKSEEMAN, That Barton intake is a very nice looking intake! I found one of the INDY Cross Rams and a very fair price, and ordered it in this week. It should work well for what I am trying. If not, then I will look at other options.
Thanks for all the advice!

DoubleD, you are correct.
The deck is milled. I can't run the sheet metal intakes in NSS. The plan is to work the intake to fit. My deck height is 10.40.

Tunnel rams are not allowed in the NSS classes I run in. I have the bottom of one of those manifolds, but not the carb section. Even if I did, I couldn't use it. Wish we could.... How would this work out, an old Weiand 2x4 dommie carb setup?
