If so, How do you like it? How would it differ in performance than a single plane with a mighty demon 850? How are the street manners?
Thanks!

on the street ? it wouldnt work well at all. if you look at the manifolds they have rpm ranges. a tunnel is for 4000-7000. you cant really drive around with that power band. i know someone who put tight secondary springs in the carbs. they effectively turned it back to a double pumper, and limped around a large single plenum. so it was for looks i guess.

+ tickets for driving without a hood, or obstruction > 6" would add up.

the performer type manifold works great on the street. do you want to bog, or burn rubber ?

I had an Edelbrock street tunnel ram on my 360 with 390 CFM vacuum sec. carbs,4.30 rear gears and a 3500 stall.It was very streetable.It did not have alot of low end torque but it would smoke the rear tires from about a 20 MPH cruising speed.

i dont get it...

if i put either 4.30's, or a 3500 stall in a vehicle, it wont be very streetable.

I ran it for many years on the street with that combo,I got alot of respect too! A 3500 stall is nothing,very streetable, the 4.30 gears just kept you from going out on the interstate.

4.30's are very streetable depending on tire height. I ran them for years with 29" tall tires, very easy to drive even on 40mile trips. I have a tunnel ram on my Hemi right now, and its far better than any cross ram or 4bbl intake I have run, but it is efi.

I have a number SB TR's as well, currently waiting to be used on my latest ride by the way, it has a 3500 stall and 4.56 gears and I drive it every sunny day I get and sometimes as far as 50-60 miles 1-way. Very streetable, and you don't even notice the converter unless you really hammer it. Then it just breaks the 15x29's loose anyways and I have to do some serious steering correction. I do have to mention that I have an A-500 with OD that helps with the gears though.

I have also run a tight 8" 4700 stall on the street with no issues as well, but it was a light car ('72 Cuda).

The bigger the engine, the easier it is it seems to run a TR setup on the street. Small cube engines seem to do better when they are set up to run with more rpm. A buddy is running a 68 Charger with a 440, Weiand TR and a couple of Edelbrooks and it runs very well and gets plenty of thumbs up. It has 3.91 gears and 3000 stall and he drives it all over the place. This guy is no dummy but is not real experienced with hot rods so I lent him a hand but it was over the phone only and he got it set up and tuned. I was pretty surprised when he showed up with it and we went for a ride. The grin factor was big. Low rise 2x4 setups have always been a hassle to set up for me and never run as good as the taller intakes do. If you like the looks of 2 carbs and velocity stacks sticking through the hood, go for it but if you like closing the hood on your engine, go with a single carb intake. JMHO.

streetable, that means to me... i can take it for a cruise. no hassles from cops. taking no cool-down stops, or overheating after 20 miles of driving in traffic. streetable...

those kind of builds usually accompany locked out timming curves, trans coolers, 4000 rpm cruising, and the mess.

if you have a set of 2 chambers, at 4k, doing 65mph youll get rolled.

i havent found a 3000+ stall ride that didnt drive like a hill billy hotrod, or a 4.56 gear that didnt cruise like my valiant in 2nd.

dragula now be like everybody else and turn off the OD. like those 29"s , then go back to 26's

a racecar is a crappy streetcar, a streetcar is crappy racecar.

There's actually one under the hood of my Dart. Sitting on a 440 with two 750 Holleys on top. 4.56 gears and a 4 spd. Streetable? Yea. But not practicle. Do I want practicle? NO. Tap the throttle and instantly blaze the rear tires.

I got lot's of friends that have 4.11-5.14 gears and big stall converters that consider them very streetable but they are as stated not real preactical. When ever they go to the strip they have to trailer them the 50 miles one way. A few of us went to a car show 80 miles away and I was the only one that drove but I have 3.55 gears and a 2,200 or so converter and my car is a daily summer driver. Most of these guy's would never consider driving their cars as drivers. Tunnel rams are okay for racing and looking cool but being practical on street? not!

Ran a Wieand TR & 600 1850s on a 451, low-end torque was no problem with 4.11s, 4100 flash stall (tons of it) & the top-end power was in a class all its own , this set-up was more streetable then my single 750 & M1, Don't listen to what some tell you about TRs , if they have nothing good to say about them, its because they NEVER ran one or they had the wrong carbs & don't know what there talking about , simple as that

Don't forget we all have different idea's of what is streetable- to me it's a car I drive as a daily driver whether it's a five minute drive or a five hour drive. For my buddy it's car that has has to run on 110 and he can't take on the highway, has to change plugs if he idles to long in traffic. Both our cars are street driven but I guess it depends what you want.

Thats nice because streetable to me is whatever I'm willing to put up with driving & legally passes state inspection!

I really don't care for single carb tunnel rams but I hear duals work well! ~Mike~

In MY opinion.... WRONG WRONG WRONG WRONG WRONG!!!

I just have to ask mark7171.... have you ever run one yourself? So many misconceptions out there that seem to get forwarded...?


I have driven TONS of tunnel rammed 2x4bbl cars over the years, so has my wife. Her daily driver was a 440 2x4bbl 1980 Cordoba LS for years, no troubles whatsoever. A baby bath carried in the trunk was tossed on the scoop during rain when parked, that was the only hassle....



My daily driven work truck was a mild 440 2x4bbl, STOCK torque converter, it had 1 ton suspension and it was HEAVY. It would roast the tires while pulling a trailer, and could do 20mph roll ons with ease.
All UNDER the hood.



Before my Coupe was taken apart I drove it for years with a tunnel rammed 440 2x4bbl. It was a result of too many problems with a single four barrel, exposed transfer slots etc. The two 4bbl tunnel ram solved all my driveability problems!



My Demon I drove year 'round from 1991 until 2000 when I sold it, I drove it in the snow, in -14 Celcius weather, you name it. It passed AirCare emissions testing with NO detuning ever. I drove it on the rollers, passed, and drove it home. Never failed once. With the tunnel ram.
Any B.C. member can tell you what a pain in the rear the AirCare tests can be too.



Notice all the vehicles pictured also had POWER brakes.

It's the combination, if you toss two 850 double pumps on a stock 360 with a tunnel ram, odds are there will be LOTS of trouble, and everybody will be pointing at the tunnel ram.
If you build a well thought out package it will be a driveable vehicle.
It's all in the entire sum of the parts IMO.


I was going to put a tunnel ram and two four barrels on my motorhome, just for the idiocy of it all, but it wouldn't fit in the doghouse.

Besides, I woulda been in the doghouse with my Chickee....

My work truck was a WORK TRUCK. tunnel ram, 2x4bbls, and driven every day all over the place, rush hour traffic, summer, winter, hauling cars ON trailers etc....

Two 450 cfm Holley center floats, they worked like a dream. Never had a better running carbureted truck.

yes ive used a tr. yes, a TR will give 30 hp or so over a dialed hot 4 barrel. the TR manifolds do not produce good velocities at reasonable street rpms. if your using hi 4000 stalls or 5 series ring gears, i dont associate those with streetable components. your combination tells me enough of whats going on.

you cannot drive around at 4000 rpms all tunnel ram and headers. the cops will pull you over.

-no a 4000 stall doesnt lock up at 4000 exactly. it does mean your not cruising at 2200 anymore.
