Anybody ever run one and like it's performance on the street? Will it clear the hood on a 57 Chevy? ( I want to run the single 4 version) Anybody have one for sale reasonable? Thanks Shane T. P.S. 355 c.i. 245/255 duration @50 545/555 lift straight drive worked worl products cast iron heads 1 and 5/8ths headers 3.73 gears All steel 57 2 door sedan
usually they don't work great for the street because you tend to lose low end power and it prolly will lose mpg too. I'm gonna run one on my 55 strictly cause I don't give a ****. They look great on a tri 5
Dont know about the Tr1 but i just installed an old Offy single carb tunnel ram on my aluminum head 302 in my Ranchero Falcon and i love it .I lost a bit of lowend torque like i heard it would ,but its only right off an idle.It screams if you hit it at 2000 rpm or higher .I am running a 4 spd. stick and 3.55 gears that will be changed to 4.10 real soon.I did it mainly for the look cuz its a g***er.It also seems a little harder to get it warmed up in the morning ,but not too bad...
I ran an Edelbrock ProRamII and two holly 650s on my '72 Chevy Pickup, 355 and double hump heads, flat tops and a Comp cams 268H. I got 16 mpg Avg. with it and it pulled real hard. I did use a 2000 rpm stall converter with a turbo 400. The hood even closed!
My little brother, Janglehead here on the HAMB runs one on his 406 SBC [now has a 377 under it] with 2, 600 holleys and aftermarket heads, Powerglide, Mallory ignition, full spool etc etc on the street and on the strip. He drives it about the same either place. Never get an opportunity to bog....runs 10.32s. Starts ok. Heats a little in traffic. Goes 140 at B'ville [2007]before spinning around
Guess I,m going to find out as I bought one for my big block 57. I also bought another hood because I,m sure it,s going to be up through. On the other hand I,m also going to buy a Thunderbolt style teardrop scoop to put on it.Should look damn cool.....
I had a TR1 with dual Holleys on my high school RS Convertible Camaro. It had a 4 speed Muncie and 3.73 gears. 4.11 or 4.88 would have been better. I drove mine year round including through the midwest winters. Use to throw a trash bag over the carbs in heavy rain or snow (when the car was parked at work or overnight). Pump the gas and hit the ignition and it would fire right up, even in 20 degree weather. It was a gas. I would say your cam and heads are a nice match for the intake, especially with a single 4. If you are running a fairly tall tire, you might want to go to a steeper gear. My 55 is running a crossram with dual Edelbrock/Carter style 4 barrels on a 358 with World Products Iron Eagle heads and a slightly bigger cam than yours with 4.88 gears. Works out pretty well, though I don't drive this one year round. Go for it.
Fast Elvis, You have a TR-1X not a TR-1. They are totally different intakes. TR-1's were probably one of the worst tunnel rams ever made. Even Edelbrock agreed and came out with the much revised Tr-1X immediately after the Tr-1 was introduced. The TR-1 looks like a giant shoebox. It is terrible on the street due to the huge square plenum. Shane, I would suggest a TR-1X like Fast Elvis's for the street. They are fairly common and reasonably priced and they are late 60's/early 70's vintage. Actually the best TR's for the street are the Offenhauser versions. The plenum was just the right shape and volumne for good street manners. .
Shane run a Tr-1x like Fat Elvis not a tr-1. Tr-1's only value is a door stop or for s**** aluminum. It was a defective design. It was the very first TR by Edelbrock. The MAIN KEY to getting a a TR to work on the street is a cam that is not lopey and one that produces the largest amount of vacuum you can find to **** down that fuel/air mixture. A mild cam works better than a rumpty rump cam. A tr-1x will not clear the hood on a 57 Chevy. Actually the TR will but the carbs will not.
Here is a pic of one on ebay (completed auction) #110211152604 I'll get you the numbers tomorrow I've been messing with TR's for 30 years. The general consensus from the hundred's of people I've talked with over the years is the Offie is the most forgiving and easy to set up for the street due to the plenum shape and runners. It was really a popular intake back in the 70's to run on the street. Here is pic of my TR setup. I'm running the early Holley 390 carbs #6299. They are discont and are different from the 390 #8007 available today.
I also have a TR-1 that came off a very quick 400 sbc that ran mid 12's......we found that this early tunnel ram worked not bad.......but I admit the Tr-1x does pull much stronger especially in the upper ranges. I have always found that carb selection is very important for "street" use. I always remember the Holley tent at the nationals back in 1980's busy with the guys that ran Holley carbs on there tunnel rams lined up to get their problems worked on by the techs. I started off with Carter 500's and now run 500 Eldelbrocks with little problems on the street. Just my observations from running a tunnel ram on the street for almost 30 years. Tunnel rams are those type of intakes you either love or hate......so do what ever turns your crank. Best of luck with the build.........hope she "goes like stink".....lol.
Offenhauser number for the base is 5921 and the single quad top is part number 5922. Shoot me a PM or call 559-592-2707 for pricing. Dan Marvin, Owner Exeter Auto Supply
Great manifold- that shoebox edelbrock. I had it under the hood of my 56 chevy. I actually, took the top off (it unbolts) and milled 1 inch off the top. Once reinstalled, you really can't notice-Not to mention extra hood clearance and maybe more responseiveness. So if you know of one out there that was milled, it's probably mine. I also had it polished which looks great. I had a couple 650 Holleys mounted sideways and it would really make the 327 scream. I didn't like the sideways mount, perhaps a pair of 500 edelbrocks would be ideal for a street machine. Go for it.
well i am new at this but im trying the same tr1 intake on my 32 ford truck with 550 demons have had it running need to do some adjusting but sounds good in the shop
The first TR (TR1) had ridges around the tops of the runners down inside the plenum. If any raw fuel puddled in the plenum around those ridges and something set it off, it made a very big bang. This was just one of many problems with the first design.
