You can tune the velocity with plenum walls, and the diameter of the runners. But they still serve a single purpose: high RPM horsepower.

Rams do NOT make more torque.

You always see Tunnel Ram specs making power between 3,000-9,000.
( Usually its more like 4,000 and UP )

Single-plane race intakes are slightly lower at the bottom of their power curve.
Another thing is "swirl". Single-plane intakes swirl better than rams.
Keeps the fuel mixture atomized better.
Rams puddle at low velocity. ( Low velocity = below 3,000 )

If you want more plenum volume... run a 4500 dominator and intake.
DART makes great intakes for BBC.

You can run a 632 BBC with pro heads at 7,000 RPM's with a SINGLE dominator and a single-plane intake.


My favorite intake for street motors is the Edelbrock Performer RPM AirGap.
That intake is the best of both worlds.
Torque, throttle response, and higher RPM flow. It does it all.

Like I keep saying, a tunnel ram on a street motor is for LOOKS.
If you like the look, go for it!

No rams make more tq and they do it high up in the rpm band. Tq does not equal low rpm.

There is no more swirl in a single plane. Now your reaching. The rams allow alot of air moving at high velocity hit against the back of the valve as ot closes and forces a lot more air into the chamber if setup correctly. Single plains are high rpm race only. Tunnel rams are actually more street able if you have the hood clearence.

Air gap is also pretty bad for street i would think the tunnel ram would be more street freindly for a lot of engine combos.

One thing they are really good for is big heavy trucks that are shaped like a brick and need massive tq at 6k rpm to get moving.

It's all about "LOOKS", isn't it.

Actually it looks like a Holley pro dominator, and the have significantly larger runners then the Weiand street rams, maybe a touch shorter, but much higher volume, and are rated from 4000rpm up......yet clearly, its the right application for him as his performance indicates. Light car, right tune, he has the best of everything,a car the goes like snot....and LOOKS damn fine doing it.....its a good thing.

I hate their yapping and gossiping.
They all think they are the queen of their own island. They think the world owes them something because they have ( you know what ).
They want to party, be the boss, and have others pay for it all.

Womens lib did nothing for society.

And the poster gals for my argument are: Hillary Clinton, Lindsay Lohan, Kathy Griffin, and SNOOKIE.

Tell me i'm wrong.

lol

I don't even know what to say......whoever she was, she did a number on you eh? Hope she was smart enough not to give you children.....especially if they are female.....and I though I was a bit of a chauvanist lol....

Mantis what did loham do to you. I love it when hot chicks become drugged out drunken sluts it increases my odds. LOL

We should probably stick to what you dont know about engines and leave out what you dont know about women that will take a lot more effort to correct.

That's one of the earliest tunnel rams built; a Holley Pro Dominator. All about looks? I drive to the strip and run in the high 7's in the 1/8 mile. If it was just looks it would probably be like many of those lookers I see doing 9. or 10. sec. 1/8 mile runs. I do like the look, but if it didn't perform I wouldn't have it on any car I owned.
Just because you don't like tunnel rams, or don't know how to make them work, doesn't mean others can't enjoy them and make them work.

Very nice car sir.

Thanks! Straight axle in a car isn't as spendy as all those fancy tubular control arms, and not much more work to install! I'm starting another straight axle car this year, and the totally rebuilt Econoline axle I found locally was $120 with all the new parts already in it. My Speedway axle kit in the Austin gasser was $800 ready to install.

Btw...I know younaernt running a moon tank....lol. it just read funny, as in "love moon tanks and halibrands".....problem with mine is its got a nova front clip and been tubbed...so re-working both front and rear wouldn't be cost effective....I would be better off to finish this one with my ghetto 70's vibe, then sell it to try and pick up something to build a Gasser out of...and I'm way to huge for an Anglia or 33 Willy's which would be my first choice....so likely would go with a tri five or even earlier.

I'm 6' tall and 190 lbs. and just get into mine past the steering wheel! If I get any bigger I'll remove the wheel and put a QD wheels hub on it, so I can get in easier! It's only 42" wide inside, and the two 19" wide seats almost touch each other!
My car is too small for a Moon tank. It would look like a huge wart out front. I had an original late 50's Moon tank and held it up to the frontend, but couldn't find a place it looked right.
I'd love some old magnesium Halibrands to replace the Ansen and ET slots I've got now. Love the slots, but Halibrands are so cool! (and spendy!!!)

Willys is big inside. And the anglia, most ppl got to screw around with the seat position usally going down and back.

A willys with suicide Door should do nicely. Tons of room inside for big and tall guy.

get you a 55 chevy already gassered up. Glass or steel all look the same when there painted. I see 55 steel bodies that have been gutted and tub pretty often. They are usally cheap so easy to find just look for the cheapest one. Seems to kill the value to have a race car that has no motor and crappy paint.

You can also get the williys in fiberglass. I think the anglia as well. But havent seen a quality kit for one.

EPIC FAIL.

You guys are so proud of what you think you know... you can't even entertain the idea of something contradictory to your own misguided beliefs.

Alot of people live in a filter-bubble. No exceptions here either.

Guys, believe what you want. Little kids believe in Santa Claus.
We believe certain things because we WANT to believe it.
It's delusional, but so many people do it. It lets ya sleep at night.

Believe what you want. Sleep good tonight! Be happy!
I'm just some loony bird who keeps saying "the sky is falling! the sky is falling!"

Hahahahahaha.

One thing about this hobby has always been: everyone has a different opinion about what they think WORKS.

I learned this when I was 16 years old, after talking to several different machinsts at different machine shops.
I was amazed at how they all seemed to contradict each other!
Ever since then, I knew what I was in for with this game.

Been playing it for years. Some things are still fun, some things are really annoying.
It's all about blood, sweat, tears, dollars, and hopefully some smiles along the way!

This is comical.

Since you don't know me, you don't look like a complete fool.
But you should be more careful in the future.

You don't agree with my opinions, so you insult my experience.
Only a fool does that.

Well more about math. Several ways to get to the same goal but its not a game or a magic spell or even santa clause. Just some good old fashion math concerning tuned intake length.

Look at it this way your average newer v8 has a tuned intake length of about 3 feet. Your 6 inch version in a victory jr is not going to do the same thing as the 3 foot of oe cars or the 12-24 inches used in tunnel rams. No as long as the pipes are large enough there is no loss in top end power.

I bet you didnt listen to your women when she tried to talk some since into you either. If you ever get a chance give one a try and see how well they work in the real world. You may find the long runners improve performance at all rpms. Really is the same shape and design as a victor jr just a lot longer runners and larger plenum. Still has the same basic effect just most car dont have the room to run them.

Got fluid dynamics?

.. If anybody ever tells me they want the dual quad tunnel ram look on the street, I always tell them GO FOR IT with the Summit/Weiand/Holley setup!

.. Hot Rod started to put up their SBC 350" 7 manifold comparison article online, but for some reason stopped at one page, instead of putting up a page for each intake/carb.(s) setup test like in the magazine... fortunately, I also have the magazine...

.. The Weiand Tunnel Ram that Summit sells in a kit with carb.s & linkage at a reasonable price is a STREET tunnel ram and perfectly streetable, including low RPM torque and good MPG (with sensible cam and gearing). Hot Rod tested it with the bottom level twin Holley 450's and said it ran perfectly right out of the box. Including, to their surprise, no unusual bogging despite mechanical secondaries, and NO DP, NO VS..!!! Summit had it a well tuned kit. It also outperformed EVERY other street and semi-race manifold at every RPM with MORE TORQUE and more HP. The only one to make slightly more top end power was the more race-oriented Eddy Tunnel Ram with much bigger carb.s (750 Dominators?), and they felt if the Weiand had been ordered with the 600 carb. option, it prolly would have beat the Eddy TR as well... but with slightly poorer low and mid-RPM performance, unless the VS's on the 600's would have helped there......

.. The Weiand TR with dual 450's would be OVERKILL, if anything, for your engine, HR was getting around 500HP from it on their 350", even bigger carb.'s would be more overkill... as in crappy running... oh, sure, it could be adjusted to sound like it was running good with dual 750's, but strap it to a dyno and it would have a sick torque curve... and waste gas doing it... I've seen numerous engines sound fantastically powerful subjectively, but put them on the strip or dyno and they fall flat compared to a well-matched combo... hell, some of them, just put a tach on them and you're disappointed..! Sure, 632 Mantis is giving you some incorrect info on street TR's, but he does make a few good points on not going overboard with mismatching things...
