The motor specs, .030+ 440, speedpro forged Pistons, E-Street heads out of the box, 9.25-1. MP .528 cam, 1-3/4" Doug's pickup headers with 3x18" collectors. Dyno is my L&S, calibrated before the pulls. M-1 single plane with Carter CS 750 Weiand TunnelRam with 2 Carter CS 750's Chrysler ShortRams cc with same 2 carbs as above. The carbs were dialed in for each intake. As expected the Weiand made the most hp, M-1 came in 2nd with the vintage shortrams trailing. The numbers; M-1 455hp@5200&507.9ftlbs@4400 Weiand TunnelRam 469.3hp@5450&542.9ftlbs@4000 Shortrams 429.2hp@5150&543.6ftlbs@3800
Now the rest of the story, the shortrams made the most torque and had the best torque average, 512.4ftlbs@2500 and just kept climbing till 3800. The M-1 was at 451.1ftlbs@2600 The Weiand TunnelRam was 469.8ftlbs@2600 I've installed the motor in my old W-150 with the Shortrams, should be a kick ass pickup motor.

Which version of the long rams do you have, long divider, medium length divider or the short dividers? I haven't heard of "short rams" before tonight

Cab, they are the shortrams set with the runner dividers only going about halfway up the port runner. I sent you a pic of it to your wansnet account Cab. Never did figure out how to post pictures here after the change.

Yep, still got the old Wreck with the TunnelRam and Thermoquad, it doesn't get out much. Been busy with a 318 and a turbo for a while. Finally decided to ditch the 318 and move to a 440. The initial plan was to dyno the motor naturally aspirated and then install the turbo. I fell in love with these shortrams and for now that's what it's going to run with. How about a turbo to forcefeed each side of the short ram?😁

I would enjoy seeing the pictures of the intake just to get a visual as I cannot picture it in my cranium. Question...quickd are you still running/driving your truck with the tunnel ram and 2 thermoquads? That has always been incedibly cool to see If you are looking for pics of the long and short ram -

there was a paper out there at one time showing how to make a long ram into a short ram. welding was required of course. the problem these days with buying a setup like that, is [almost] everyone loses the pieces that cover the crossover port in the heads, allowing the intakes to bolt to opposing heads. those parts were just cut out between the bolt holes with a band saw, making the cut pieces unique to each manifold. at one time, there was someone reproducing those pieces and they were slightly oversize, allowing trimming at the bolt holes to fit the manifolds on hand. i don't know if they are still available today. the balance tubes also somehow disappear as well. they are a neat induction system. i wonder how much torque a 500 plus cube engine could make with a short ram setup at, say, 2500 to 4500-5000 rpm, and let the horsepower fall wherever it does. that might be fun in a 2500lb hotrod with big tires and a 3.23-3.54/3.55 rear gear. [like my "perpetual" project]

The turbos would negate the design. I would have to argue on that one. I would love to see what two small turbos on mild boost would do. Quick spool up, run e85, no intercooler. Say 7 psi?

Very neat, thanks for sharing the results.
What turbo will you be using? (assuming different between the 318 and 440)
