who is running a single 4 carb tunnel ram on a sbc what cam and carb are you using i got a team g super ram with some parts thinking about putting it on my 327 what is the pros and cons
Not a Chevy ,but i ran a single carb T-Ram on my 302 powered falcon streetcar a few years back.I ran a 600 Holley with Vac. secondaries and a small hyd. roller cam of about .490 lift.The only problem i had was lowend torque loss over ,but the high rpm power was amazing.I drove it year round in everything form 20 -105 degree weather.Are you gunna be running a stick shift or an auto ,what gears? You may not like it with an auto trans and stock street convertor off the line.I ran a 4 spd and low gears with mine ,so that wasnt a problem ...
I would think its better suited for higher rpm's if thats what you intend to use it for.Theres probably better choices for a street friendly 327 but I'm sure someone will correct me if I'm wrong.
I have an Edelbrock 600 cfm with Electric choke (1407) on a tunnel ram on the Willys with 383 stroker - could do with a 750 though.
If your gonna run a tunnelram and a single 4.....go about a 650....dual feed vaccuum secondary, with the gears your running....you can go doublepumper....just tame down the accelerator pump on the front 2 and play with the powervalves some....you can tune it out pretty well.....if your gonna go more the .500 lift and 250 Degrees @ .050....run the Rhoads variable lifters....it'll calm the cam down some....then when rpm comes up...it'll go into full lift. The Gears and trans setup will be fine on your setup. I ran tunnelrams on the street for about 15 years with no ill effects. Now ya gotta tune them....they're a ***** to get set, but once there....all you gotta do is keep her tuned up. Pretty much it.... Mine was in a shoebox Nova with a 283, tunnelram with small dualfeed holleys, rollercam (fairly mild...260 @ .050, .550 and .575 lift), 11.5 to 1's, good heads with 2.050 intakes/ guideplates and screwin studs with jomar bars, headers, pete jackson gear drive, 9 qt drag pan, and a 4 speed with 4.88's out back.....with 33x15 M&H Racemasters, ladderbars....you know the drill.........
Sounds like it should work out to me with that convertor and gear ratio .Agreed on everything Screaming Metal said.It just takes sum tuning to get it right on the street ,but once you get it tuned right you will like it (i did).The reason most people have a bad opinion of T-Rams on the street ,is because they put one on a stock smallblock with 3.08 gears and no stall in a heavy car.That scenerio makes for a real dog with a T-Ram.Lite car ,mild cam ,small carb or carbs,and fair amount of stall or stick shift with pretty low gears works well with a T-Ram on the street IMO .Good luck with it ...
Well I'm not sure what intake you have. The Team G series of intake manifolds are not tunnel ram intakes. They are a hi-rise single plane intake manifold, much shorter than a tunnel ram. Weiand has several different styles of tunnel ram intake over the years, but I do not recall a Team G tunnel ram, but I can be wrong. Can you post a picture of the manifold? This will help us better to suggest what you might need to make it work.
Sure as ****!!! I have not seen one of them. Honestly, the plenum is small which is good, but this might cause some unbalance/distribution issues in the end intake runners. Could be why not many of these are out there. It would be cool to see what the inside of the plenum looks like. The runners appear to be quite big, how big are they where the intake meets the head? You for sure will want to at least gasket match the intake to the heads. As far as carb goes, I'd go with a holley 650 dbl pumper with four corner idle circuits. This will give you the best tuneability and best chance for equal distribution to all the runners. I've never been a fan of single four tunnel rams for the sole purpose the ditribution is poor to the end runners, the dual carb ones do not have as much of an issue with that. I am a huge fan of dual carb tunnel rams when the engine is setup to support one correctly. Tunnel rams can be very compatable in tq and hp as any high rise style intake manifold if engine is built accordingly. They can and do work great in street driven vehicles. Is the 327 basically stock, or what has been done to the engine(cam, heads, compression, etc.). I think this intake can work on the street ok, it will for sure like the upper rpm range. It can be made to work, and you more than likely will be ok with it, but if you are looking for performance/driveablity more than appearance, then there are much better setups to run that will be much easier to set up and run. If the engine was built to have the tunner ram, then of course it will perform well.
right now the motor is standard bore but it will clean up at 30 over. heads are 462 with 202 valves trying to get some info before it goes to the machine shop i also have the 2x4 top that goes with the intake just want some info from people who has done this before i want to run pump gas so i can drive it
The end cylinders tend to run lean on a single 4 setup, I have heard of using extra lift rockers on the intakes of the end cylinders to promote better cylinder filling.
Personally, I'd go with the dual top. It makes it much easier to tune and get set up properly. What are your plans for cam and compression?
do not know about the cam yet frist time using a tunnel ram that is why i need info on what cam and carb others have run with good results have 3 2's on a 327 on my 63 nova and they were a ***** to get set right but it is a 4 sp car not auto
Here are the specs of a 335(327 bored .060") I built for a street driver OT ride. 10.0-1 compression, 180CC intake runner cyl heads(they were ported to get this cc size) Isky hyd. flat tappet cam grind # 524(this is listed in thier circle track grinds) 1 3/4" primary tube headers with 3 1/2" collectors. Weiand High Ram #1984 dual quad top, holley 650 double pump carbs. These carbs I built for use with a tunnel ram intake, NO POWER VALVE, and final jetting ended up at 78's. This engine has a sweet lope at idle, 800-850rpm idle speed, and runs amazingly strong all around. The peak dyno numbers were 501hp @ 6300rpm and 441tq @ 5400rpm Tunnel rams can be very successful on street driven engine, but make sure the build is "matched" or they can be miserable.
