trucks with tunnel rams

I bought my self a 2007 monte carlo to be my daily driver. I am thinking about doing a tunnel ram on my big block. How about some pics with tunnel rams or even more rare a cross ram.

Re: trucks with tunnel rams

edelbrock TR1Y in my 57 with a 68 327 in it (ok, my 57 in 1983, that is... but still). Yes, it was sporting 70's yellow accel wires, Holley 600 vac secs, Muncie 4-speed, and what I thought was a really cool Mallory dual point

And, for what it's worth - I'll never do that again! Not exactly streetable. You'll hear plenty of folks say it is, but it depends on your definition of "streetable." Yes, I could drive it just fine on the street, but it was like cop fly paper, nil for gas mileage (not that you'd expect any anyway), and it is not designed for stop light to stop light. Well tuned, it ran a little better, but still was a pain on the street - those things are made for mid-high rpm, at the drag strip. If you do it, highly recommend smaller carbs like 390s or 600s (max).

Don't get me wrong, not trying to discourage your choice - I LOVE tunnel rams, but just be aware the pain that comes with them, that's all.

But having said all that - it was a real screamer when IN its rpm range...

Re: trucks with tunnel rams

I really want a cross ram for my truck. A pair of 450cfm Holleys and lots of tuning with my wideband O2, I bet I could get decent mileage out of a combo like that.

I did a pair of Edelbrock 500cfm on a 482ci BBC in a 70 Monte Carlo and it got 14-15 mpg on a mountain trip to TN. Dual carbs can be streetable, you just have to work at it. Its not going to just bolt on and work.

Re: trucks with tunnel rams

I found a edelbrock c-96 crossram intake today for 100 bucks. Anyone running one on their truck? Some piocs would be cool.
