I had a tunnel ram once, on a 65 nova. 350 power glide. Put it on, went for a drive when it hit second gear it went sideways off the road into a field of scotch broom. That was enough for me.

We ran the same tunnel ram and 450's that you are talking about on our 355 with a lunati voodoo 60104 cam. It ran absolutely FANTASTIC! We actually have the entire setup for sale right now.


All I had to do to get the "lean bog" tuned out was install 50cc accelerator pumps on the both 450's. It drives fantastic on the street and makes a ton of power. Watch this video of the car to see for yourself.

To answer Jester's posts:
Thanks you for all your, and everybody else's replies as well. I have rebuilt many a motors so far. Stock ones that is. High performance (especially carbureted high performance) is where is still have tons to learn. I am 27. The more i learn about modifying engines to squeeze hp out of them, the more i realize how little i know about that aspect of the automotive world.

As everyone said already, and i understand fully - tunnel rams are high performance. They look cool, but if you can't walk the walk, go back to the drawing board and recompute. That camaro - i only use as a toy. I only want tot take it to the track and turn it loose see what it can do. Obviously i want to go fast (Ricky bobby style ), but i dont wanna look like an idiot. Esentially - it would look real cool when i show up at the track with a scoop sticking through my hood but if end up doing a 30second quarter mile after redlining my motor im gonna look like a real @$$hole.

If i can get more power from a dual plane intake and an edelbrock carb, so be it (it ll save me the trouble to cut my hood and ill be able to see out the left side of the windshield lol). In other words - what would be my best option to make power out of my setup, even with ditching the T-ram? What would be the most sensible way, using what ive already got, to have a decent machine?

As always, thank you everyone for all the great input.

Mavrick: I just built my wife a 302 like Smokie old school its at the dino now I set it up and make my changes with a single quad, single plane ram style high rpm intake get it right the way I want it to run and then go to the tunnel ram as my final set up, then when I tune it in, I pretty much eliminate everything that could give me trouble except for the induction system & dist curve & tune it from there! you dont need a dino for this.You can do it at home installed in the car! Run any good intake and carb that matches the rpm and demand of your build run that on street or track you should have very good time slips! You can always build a tunnel ram set up and swap it at the strip or at home it doesn't take long in the pits or home and it doesn't cost much (just gaskets) once its set up Remember to run a distributor that will fit behind the ram. If the ram is set up with a different curve get a second distributor to run!

You mentioned scoop: When you race don't run air cleaners in the scoop & you should make a bug screen though on the front ( I sucked a black bird in at 130 miles an hour once LOL ) that was a real mess!! Make sure your scoop is in the air streem at speed you dont want a low pressure area at the scoop inlet It will pull air away from the scoop starving your carbs!! don't take for granted that an over the counter hood or prefab scoop is fine because they usually aren't. seal the carbs to the scoop any gaps defeat the purpose of the scoop.

This is the scoop I made for a wieand high ram with hollys and air cleaners the little rize on the side gives clearance for my fuel line .Its in the air stream and I see fine! if Im at the track I pull the skull just 2 screws ( ran it once with the skull and deflected air away and slowed the car) My cars not pretty did a lot since those pictures were taken Too!

The pictures of my set up is in my gallery. I have 4 sets of carbs for my car over time youll have a lot of different set ups and a garage full of parts! your still young! Wow 27 LOL I hope I have 27 years left

Jester: i meant 24 actually lol. The 4 is under the 7 on the number pad(oops) - i was typing really fast while i was at work so the boss wouldn't see me on company time (we had a few cars that needed attention at the time). DOB - July 13 1987

So you guys think i should keep the T-Ram and try to tune it as i go huh?

Also, Jester - the advice about not running filters while at the track - very obvious, yet very good. Never thought of that. Makes perect sense , although i never thought of it. A big duh is gratiously awarded to me. While not trying to sound ignorant, these are the tips and advice i need from the more experienced guys out there. Ive been at the track hundreds of times and raced, but it takes experience and advice from the seasoned vets of this game to get ahead.

lol

so any advice on what to do next? Since the motor is on a stand now,and easily accesible, should i swap out the cam? if so, to what? any course of action that i should take with the carbs?

ProStreetCamaro, that's actually very impressive. Setup looked like it worked pretty good for you.

I am rebuilding a TH350 tranny at the moment (its in the sopgetting hot tanked as we speak). Any ideas?

Once again, i can't stress how awesome all the input everyone is giving me is.

I like tunnel rams, cant turn down a photo op

As pointed out earlier tunnel rams like alot of initial timing and/or even locking them full. As for carbs the "mild" type build might want to stay with the smaller carbs. I prefer double pumpers 650's on up depending on app.
When working on the 450 carbs found running the 50cc pumps beneficial. With that acc pump & cam will carryover the pump shot into the secondaries when they start to open. Each application is different and your results can vary.

lg1969 - after doing more research, based on what everyone told me, and also the articles FBird and Jester told me to read up on, i stumbled on an old post of yours from about 5 years ago, from a post somewhat simmilar to this:


Quote:
Tunnel Ram setup

--------------------------------------------------------------------------------

You guys are still questioning if Tunnel Ram can run on the streets. I can tell you this YES.
I have a 69 Chevelle ever since my mother bought it brand new. I have own the Chevelle for 38 years and still enjoy driving it all over the Island.
Out of the 38 years of use, I had my Tunnel Ram setup for 25 years.
It is sitting on a 10.5 :1 compression 355cid with 2.02 heads, Crain fireball Cam, 1.6 roller rockers, with gear drive. The carbs I am using are modified Holley 390CFM. They converted from single feed to dual feed setup with metering block for my secondary from a 780CFM Holley. They are mounted sideways on a Edelbrock Street Tunnel Ram.
The jets are 57 for primaries and 62 for the secondaries, and 6.5 power valve.
I use a blue pump cam on number 2 setting.
With this setup I even passed emission test before the law was change to safety inspection.
Now I got a 11:1 400cid SBC with AFR heads, Comp cam 270H the same 1.6 roller rockers and yes, gear drive. My 355 had so much low end torque, I can pull tree stumps. And now with the 400 I can pull a house. ( Only Kidding). The Chevelle pulls like a jack rabbit. Top end it will make your hair stand. The 400 is coupled to a 350 Turbo Hydro with 3000 stall converter with a shift kit, and a 12 bolts 4:10 gears for the rear end. As you can see, Tunnel Ram Setup will work with no problem.

--------------------------------------------------------------------------------

Do you by chance remeber the specs on that 355 you had? Cam specs maybe? The numbers you are bringing up on you part selesction seem crazy enough to work on what ive got...
Also, not to be an @$$hole or push the envelope too far, but on that same 355 setup, do you by chance have any track times or hp numbers? Thank you very much in advance.

Jester and FBird, i think them articles are helping

I'm not to sure but it was .448/.448 lift with 1.5 rockers, 222@ .050, advertised duration 296/296. 109* sep. I used 1.6 Rocker which makes it 477 lift. It is a strong midrange cam. Slight lope to it. I used it on my 307 (30 overboard) and on 355sbc. Both used 64CC 202 heads that was used on a 69' 302 Z/28 engine.
The 355sbc was 10.5:1 compression. 3600 pound car I was doing 13.2 sec on the 1/4 mile with my 307sbc with street tires. Before they shut down the track. Now there is no 1/4 mile track here. I never had the chance to try it the 355sbc.
BTW: The 406 is using a 280H. I pulled the 270H. Too mild.
And you are not an @$$hole at all.
