Not to hyjack the thread. Anyone have any experience between the Barton/dominator combo vs an Indy tunnel ram or a mp cross ram?

My $.02, I tried an Indy single plane and a 1140 cfm dominator vs a old Weiand 2x4 tunnel ram back to back on the Dyno. The motor was my 605 street Hemi. I do have to admit the Indy intake was to small for the motor. The best pull was 787 hp with the Indy. The Weiand and 2 Thermoquads made 852.8hp and alot more torque from start to finish. I don't remember which intake the Indy was but I gave it to Dragula and maybe he knows. Most people don't run a tunnel ram because of hood clearance or just are to lazy to want to mess with 2 carbs. I made 18 pulls getting the Thermoquads dialed in and I feel it was Well worth the time. I for one will never go back to a single carb. Do you still have the factory plenum on your weiand? I have one of those, there just so damn talk then the plenum seems small.

Lee after reading this I think you need to step back and look at what you want the car/engine to be.
Stock looking? Fast? Drivable?
"My car is 98% street and highway driven, so that is where I am coming from and looking for solid advice as I don't want to give up any horsepower for the simplicity of a single carb."
Sounds like a EFI conversion would make the most sense.
You are asking for advice on a racer forum so Dave Hall gave you a racers perspective, no reason to get butthurt.

I have converted more than one dual quad Hemi motor, both early Gen 1 Chrysler Firepower and the newer 426 Street hemi motors from progressive style to one to one, that really wakes both type motor up Especially at low RPM part throttle, under 2000, in gear The Stage V EFI hemi intake is a single plane and it will have both throttle bodies opening at the same time, hence 1 to 1 ratio I'm sure this combination will make the owner a little gun shy and nervous by the throttle response and tire spinning at WOT, not like a stock street Hemi motor with the progressive linkage

Just a short answer to the 4150 single 4 . I used a Race Demon RS 1050 Yes it will support 700 HP. 572" 10.5 - 1 stage V heads by MCH Comp solid roller .660" .639" 264* 270* @.050 112 lsa Pump gas. 2950 # 5.98 @ 115.73 I have not driven it a lot on the street , but when I did it was flawless. That said, I decided to go bigger.

"Dual throttle bodies on a Stage V intake would be the perfect combo for power plus drivability" - Andy said that to me about 7 years ago and I listened. Check out the pump gas dyno run from MM: https://youtu.be/95gZTspdzsg It gets interesting at 0:20. 888 HP at 6400 ... and who knows what the torque peak was since the recorded peak was 828 when they started measuring at 5000 RPM. Maybe it made more at lower RPM? I took delivery back in June 2017. I started collecting parts 10 years ago for this bucket list project. Some of the details: * World aluminum block * Stage V Heads with CNC port by MCH 428 CFM at .700" * Callies Crank * Oliver I-Beam Rods * Ross Pistons (10.8-1 CR) * Bullet Roller Cam (.637 lift, 273* at .050, 114 separation) * Comp Elite Lifters * Barton T&D Rockers * Stage V 2x4 intake manifold * FAST EZ-EFI 1.0 dual throttle bodies and ECU * AR Engineering Stage V dual quad throttle linkage kit * 28* of timing, 50 Lbs fuel pressure * FAST XFI 2.0 and XIM coming soon and some beadlocks I'm buying parts for the new fuel system now and I'll need some headers. My 18-spline A-833 will also need an upgrade. It's a Back-half 'Cuda, lots of fiberglass, Dana with Strange Axles and big ET Streets. Coming to the streets of North Pittsburgh as soon as I can get the rest of the $part$ and fabrication taken care of. Special thanks to Mike, Eric and Scott from MM,Jeff (RIP) at MCH, AndyF and RichN for lots of advice on getting to this point.

I have a Mopar Crossram on now but low speed drive ability is poor. I'm a street driver as well, love power tour. Was looking at the edelebrock 2x4 intake vs the Indy single. I found that Pro System does a Fantastic job on carbs. Not sure if edelebrock is spaced for Holleys? Efi is the best drivability. Anyone try FI tech on a dual 4 intake? I haven't tried throttle bodies on a crossram but I bet it would work better than a pair of carbs. The carbs get messed up by reversion while the fuel injection would not have the same issue. If I had a cross ram car I'd try a pair of throttle bodies first to see how well it worked. If I couldn't get it to work then I'd switch over to a Stage V intake since I know that combination will work.

Here's why the Stage V will work okay for you. This one is untouched but with Tim's CNC'd Stage V heads. Knowing what I do now I wouldn't have wasted the time with those AVS'.

FWIW...the only thing that will make more power on a big cube hemi than the Barton single 4500 manifold or the big Indy 426-4 manifold is the big Indy tunnelram or a custom sheet metal tunnelram. Keep in mind that there are 3 different versions of single carb, single plane, Indy hemi manifolds.
A good dominator is plenty streetable. I have a Pro Systems 3 circuit 1200 cfm dominator on my 572" pump gas hemi that's been 9.54 at 140 mph on motor and 8.91 at 150 mph on nitrous at 3900 lbs. I use the Barton single 4500 manifold.

I run dual Holley 1050 Dominators on a Indy Tunnel Ram on my 528". We did plenty of idle, cruise & WOT adjusting & tuning on the dyno. Totally streetable & makes nice power. Motor was built for the spray anyway for at the track. My next big upgrade someday will be EFI & 4500 size Throttle Bodies.
