i didn't think it looked to bad but what ever thanks for reporting me to the mods there richard about my coment on your post count . no body likes a nark
Run one on my Model A tudor. Has to warm up a bit on cold days, but so do I. Looks great to me and that's all that matters. No problems with tuning.
Sometimes you have to give up a few pleasures of like easy starting no backfires, melted air filters to name a few for looks. Some times you need to bend over backwards. Gary M
My Offie 360 2X4 intake was a single plane intake. Granted it wasn't a T-ram but I didn't have any tuning issues. I've tried many different ways to set idle mixture but I find the best way is with the time proven vac*** gauge. Matter of fact I have mounted in engine bay so I can see it while tuning. Before I start I disconect all the linkage and back off idle screws until both carbs primary throttle plates just close. Then hook up linkage carefully so there is NO BIND.. Then I screw in the idle speed scew 2.5 turns and mixture screws out 2 1/2 turns from seated positon. Start equal on BOTH carbs.. Start up and let warm up !! With va*** gauge on make adjustments for best idle & highest va***m What ever you do to one carb..duplicate on the other...small adjustments each time ...ie:..turn front idle screw in 1/4 turn....then turn rear idle scew in 1/4 turn..keep it up till you get the idle you want. I find I wind up with a very good idle and plenty of off idle response...no coughing,poping,farting, whatever !! I can smoke the 9" slicks at will... If you are running AFB carb you may need to put in weaker rod springs to make sure primary side is not running rich due to low va*** signal..capieceh !! Takes time ...but hey ...it's worth it. I have several buds who drive t-rams on street with no problems... It helps if you have a big inch motor....350-400+ cubes. Don't over carb !!!
RD - Here's the first aftermarket tunnel ram that was available. Edelbrock TR-1. This shot is from 1968. My guess for the release date would be 1967, cause I had a speed shop at the time, and we got this one not long after they became available.
Ive got an old Weiand TR stashed away for the Austin. I would gladly swap it out for a vintage FI setup if someone's willing to donate.
I saw the 'enhanced' version of 2 lane blacktop and it was told that IT WAS THE EXACT SAME CAR!!! so what's the argument? I have a long ram manifold on my datsun engined Cricket; it runs like **** cold due to the fact that the fuel pools, the time of travel is too long for proper atomization at low speeds; high speeds aren't a problem....this is the exact purpose for what the tunnel ram was built for oh; and it's NARC
ok, the smaller plenum and runner tunnel rams are one thing but the TR- series is another animal all-together. I tried one for about five minutes took less than that to realize this manifold is not the manifold for my setup.. put one on the 454 with two Edelbrock 600 cfm carbs it was tough to start and when it did in no time the front header tubes turned bright orange.. shut 'er down and swapped to something a bit more tame
Not really a tunnel ram, but anyone here have experience with the old Edelbrock Rat Rooster intakes??? Drivability vs. performance compared to a t-ram? Offy had T-rams available late 60's as well.....Port-O-Sonics......*I think
Tunnel Ram is a generic term these days. The driveability issues increase with plenum volume due to the resulting loss in intake velocity. GM used a tunnel ram on the TPI cars. It was just made with small diameter runners that were folded around the common plenum. When they put together the LT1 EFI that followed they shortened the runners and increased the plenum, raising the powerband of the engine. The chief issue with increased plenum volume and the resulting drop in velocity is the fuel distibution irregularities that come with it. Fuel Injection solved that. If you choose the right size runners, correct size carb and appropriate cam, none of these are too major. If you slap dual 750's on a big open plenum tunnel ram and feed a stock smallblock, you won't like it. The same issues arrise with a big carb on any single plane. Just match the components and they work fine.
I vaguely remember a story/article about a guy with an early Nova with a tunnel ram under the hood. He basically modified the thing to get it to be hidden and have a broader range. As I recall it worked very well, or was reported that way. I only like em on old pro stockers. For some reason to my eye they appear almost childish in many applications. Not all, but many. Especially when the Mr Gasket 3 hole **** pile scoop is added. Redneck childish at that point.
Rich, if you want a tunnel ram, run a tunnel ram, you are not building a traditional car. you are building a hotrod. I have seen some different articles on different tunnel rams and some work good and others are ****. I have one of the first versions sitting on my shelves. I have heard the summit tunnel ram set up runs pretty good. (like it was said above, they are cold starting but can be fun as hell.) I say go for it with 450 cfm carbs, just build that 327 to spin some high rpm's.. and you will have a smile most of the time..
I've seen enough of those HILLBILLY BLOWERS to last a life time. There is a certain "LOOK AT ME" factor that usually comes with the tunnel ram equipped car. Maybe because so many ugly street cars have run them they just have a permanent bad taste for me.
A ctually Discs were showing up on cars as far back as the '50s that I know of. Well actually so did tunnel rams for that matter. As far as everyday over the counter stuff both came along later than that. For the most part anything can be tweaked and be streetable. I think the reason the tunnel gets knocked down is exactly what jim said, they are pretty much a later the '65 thing. And pretty common place in the '70s era.
On the "right" car they are beautiful (g***ers, street machines), but TOO MANY of the schlock-rods and Rudy-Truck wanna-be's add them on for extra VISUAL IMPACT along with the ****py plastic mailbox on top and the peeing dog attached to the tire. Most often looks like one of those tuxedo T-shirts at a wedding- stupid.
I believe that I have the right combo of parts and I also used the small 450 Holleys View attachment 263356
Are you trying to say you were running lean ? Can't blame that all on the T-ram..you wern't getting enough fuel for some reason..or to much air (leak) ..IMO.. Street or strip you just have to match all the components up for them to work well...plan ahead. FWIW: I run AFB Comp 750's on my 462 Pontiac with stock AVS valves......NO PROBLEMS. I trust you know what a AVS valve is ?...or I rest my case Different strokes for different folks...
I have tunnel ram on a mild 355 small roller tko 600 and 4:88s I love it works great just have take your time and tinker with it.
I ran a wieand tunnal ram 2-600 holleys on LT-1 350 4spd 331 posi in my 67 malibu on the street every day [ execpt snow] 81-86 !!! Everyone loved it!!!
Alot of your responses seem to have come from guys who have never actually RAN tunnel rams. Or guys who didn't put together a "package", they tossed on a tunnel ram, two carbs, and tried driving. I've ran tunnel ram intakes on all sorts of vehicles, from my Coupe to my 365 day a year driven Demon, from my daily driven WORK TRUCK to my wife's daily driver. Tunnel rammed 440, two 450cfm center float Holleys. Daily driven ClubCab 3/4 ton with 1 ton suspension, mild hydraulic cam and STOCK torque converter, it could spin the tires for blocks. No trouble with cold starts, no difference in gas mileage than my 800 Holley I replaced, ran like a top, and I towed a trailer with a car on it quite frequently. TONS of torque. My Demon was a healthy 440 with an M1 tunnel ram, it was driven in the snow, started right up in the middle of winter, no cold driveablility issues at all, and p***ed B.C.'s AirCare emissions testing year after year, for 9 years in total, without ever detuning in any way. It never failed AirCare once. Wife's car was a daily driver that ran smooooth as silk. Lastly, my Coupe, which was daily driven in the 80's, and street POUNDED regularly. It's the reason I went to 2 four barrel intakes in the first place- it had a healthy 440 and would never run right with the 850 dp I had- turned out I found out later the carb needed to be opened up enough at idle to stay running the fuel slots under the throttle blades were exposed. I could have drilled a couple holes in each primary blade and probably solved my problem, but I didn't know at the time and tried the tunnel ram. Worked so well I was hooked for a couple of decades! </many times told story>
Been running a tunnel ram on my 55 for almost 30 years ....it's all in how ya build them....and I drive the wheels off of it with few problems. So build what ever you want, it's your ride....enjoy!!
Falfa was takin' Milner. Milner said so himself!!!!!! Therefore the ***le of "Graffiti Coupe" shoulda been p***ed to Falfa.
