Tunnel Rams For The Street?

Hey guys are the combination of Tunnel Rams & Street cars as dead as Disco & Lime Green Shag carpet or alive and well like the Pro-Street movement ( Car Craft & Hot Rod have declared it dead time & again only for it to return)?

I seem to be seeing alot of Tunnel Rams at the car shows lately.

I know Tunnel Rams aren't the mileage miser part but I hear they help the heads flow 30% better at the expense of MPG.

IF you are willing to put a 4.10 or steeper gear in the rearend. Stop listening to whoever told you about the 30% better flow.

Who said Tunnel Ram is dead? I see them at the cruise nights all over the Island. I got one in my Chevelle.
I got a Car Craft magazine stating it's in vogue.

I have a Edelbrock Street Tunnel Ram (oval port) on my 400hp 454 with dual AVS 600s in my daily driven, rain or shine 1500 truck. The truck runs like a dream and at 70mph, with 3.73 in the rear and no OD, I get 12.5 mpg. With the old dual plane dual quad intake I had on there, I would get 8mpg. Now no matter how I drive, full gas every stop light, 3,500 rpm on highway, etc, I can not get below 12.5 mpg. If I baby the highway speed at 55 mph, the truck gets a tad under 14 mpg. Whats more, is that it actually take less time to warm up, not the intake ,but I mean I can stomp on the pedal after only a minute or two of the engine running and get no stumble or grumble, unlike the dual quad intake which took as long as 20 minutes.

Better mpg, as much power, and all round better street manners, you could say that I'm a fan of the tunnel ram. The only con was that I had to cut the webbing out of my hood for clearance, and I had to add lead to the airvalves on the carbs to get rid of a stumble.

You might have to re-curve the distributor, on my 454 9:1CR, I set the initial at 36, with all in by 3,000 rpm.

machinestheman,
Please don't take this as a knock, but it looks like you're using some type of plastic/ vinyl tubing as a fuel line. It's not a good idea to run fuel through it- that tube has no heat or abrasion resistance, plus I think gas will eventually break it down.

You can bend up some new steel/ aluminum hard line and connect to the carb feed line with a short rubber hose, if you can't afford braided stainless or push-lock fuel hose...

That setup would never pass tech at a track. That stuff you are using for fuel line is "beverage tubing" made to run colas' and budwiper thru..

Seen it for many years. Threw them all out.. Disaster in the making Not on my watch..
