So I just picked up a set of long ram intakes and now I am wondering what I am going to do with them. They are the real long ones divided all the way to the carb. How well do they idle when very cold? Seems they might not want to run very well and would have bad fuel seperation at really low speeds, I am talking even before the heat tubes get things warmed up. Will they fit a 76 cordoba with a 400? If not a 400 how bout a 440, seems you would get more room by bringing the carbs up and in  Any one know the cam timing they are supposed to work best with for low RPM TQ?

IF EVERYTHING is stock and functional, they run great! If items are changed and modified it's case by case.

Not sure, MAYBE

It all depends on the rest of the build. Scott Brown made one for mine and it rane excellent making as much or more power than the factory rating with a stock type build.

The intakes were designed to make big low-midrange TQ to get the big cars of the day moving along quickly from a dead stop, something they did a VERY good job of doing. The Long Ram intakes having divided plenum runners their entire length made big torque but peaked quickly, they were all done after about 4,000rpm. The Short Ram intakes (same physical length but with internal runners only partly divided) make peak torque about 1,000rpm higher and were more interesting in a racing application. Peak torque and HP was fairly similar between them, WHEN they made peak Tq/Hp was what was more important to note. As far as outright potential? Hard to say, but you have to keep in mind that even though they offered tire melting TQ, they were not a "drag race" intake like the later Max Wedge and Hemi Cross Rams were designed for, The Long and Short Rams ran out of steam too soon for most high reving drag racing applications.

I owned Maverick's 60 Dodge PHOENIX. It had short rams and went 13.74 and 104 at Lions on street tires when traction on the street was better than at the strip. I shifted at 6000. Maybe I was too dumb to know that they ran out of steam at 5000. sure had a lot of fun with that car. I beat a 64 GTO in Denver and after that no one would race me. I've often wondered what it would have done with slicks and a higher stall converter

Here is a dyno sheet from one of my Long Ram engines, rebuilt to stock specs but with better componants (stock stroke, 9.5:1 lightweight forged Diamond pistons, stainless valves, good valve job, Scott Brown hyd. roller cam, roller timing chain, etc.). We plated around with timing, HP peaked at around 405 and TQ at about 525, but the timing on this sheet seemed to net the best average.

I was looking around on the google machine and found some old dyno sheets from around 1959 of these manifolds and seems they were running timing around 32 33 degrees, I was a little supprised but you did not find they liked much more. I wonder how they would work on a 440 with better heads, compression, quench and headers

Couldn't hurt, neither would a bigger stroke, keep in mind that mine was basically a blueprinted restoration type build with general parts quality improvements, not neccessarily looking for HP gains.
As far as the timing it "liked" the cam grind has everything to do with it.

On my 60 Plymouth's first outing this year (with 'short' long rams), I initially shifted at ~5800. My engine builder said I should be shifting at 6500. That lowered my ET from 12.89 to 12.79. Tell us more about the The Maverick Phoenix. Quote:

I have a set of longrams on a 500" stroker with 10.5:1cr Edelbrock heads and shorty headers, dumping into a dual 2.5" system.
The exhaust is not optimized for high-rpm flow as most of the bends are pushed-in about .5" by the tubing-bender.
At first I ran the engine with a stock-ish cam (one step above stock) and 1.6 rockers.
It made gobs of torque which made my well optioned 1960 NewYorker feel like it was a 3000 lbs car.
Last year I decided to try out a CompCams 'XR274 R-10' rollercam in the engine, but things have not been so good since then.
With this cam in the engine I cannot adjust the timing to my liking. I've flattened the curve with 2 of the heavy springs in the ignition but when getting on the throttle while having more then 20-22 total advance, it will detonate at 2000rpm and higher. This is all running on our local 98RON fuel. Which is about 95 octane in the US I believe.
I think the longrams and the cam just create too much cylinderpressure at those rpms.
I've also installed 2 AFR-gauges in the car to monitor what's happening in the engine.
At the moment I can't think of anything else besides putting the first cam back in the engine again.
