    Ralph Ridgeway T ram. The first commercially cast and sold T ram. The first T ram was built by Carroll Caudle made from a SBC Rochester F.I. unit that was sold/given to Edelbrock that resulted in this fine piece.



    I sent a picture of the Ridgeway t ram to Steel awhile back. As I remember his words were something like "WTF were thinking"

    The idea of port "tuning and plenum volume" was lost on that thing.
    Caudle fully understood port length tuning. That's why he used the Rochester F.I. unit.
    Edelbrock understood it was well, but went about it is a very odd way at first. Caudle was against the idea of the raised runners in the plenum. They(Edelbrock) were very concerned about raw liquid fuel going down the port as you can see. More than a couple Edelbrock TR1s blew there plenum boxes apart before people started filling them with stuff like casting resins.

    If you think Ridgeways T ram is a bad design, you should see his rocker stud girdle design. And he marketed the first stud girdle as well. First, but very seldom the best

    That looks like a nightmare for a gas deal but if you had it cut down and tossed a hat on it with a fuel of your'e choice it could work " as it sits with carbs " forget it unless you plan on running in the 5 digit range all the time. Thats more plenum than most engines could handle! GN-7 could enlighten on that arena!

    Couple throttle bodies and 16 efi injectors in the runners wld make for hella blowthru deal.if you guys say the guy was a sharp runner length tuner it might work for efi????? Put no fuel thru the plenum to puddle.

    Dare to be different, if it turns out great you can claim you planned it that way.

    Understand the point but if that deal was to be cut down about 6 inches and cut for a hat it could be a good deal on methanol or even a nitro mix! All depends on the engine it sits on! Could be fun to tune! I am kinda sick in that area and love to tune that kinda crap. O.F.

    Stuff has come and gone where your just know that they didn't get the concept. I have no idea how many of these Offenhauser sold, but it was more than a few. Again WTF????



    Like I said, Ridgeway pioneered the commercial sale of double bar stud girdle. Anybody see major flaw in this design? He was great at commercializing others ideas, but he some how failed to grasp the concept of the idea. He sold a few of these as well.

    That manifold is a sad attempt at a cross ram? Basically would create a plenum like the box ram! Chevrolet and Chrysler tried them and worked for a high RPM deal but on a marine engine I don't think so! Might be better off sticking with the box ram. I played with a 440 wedge years ago and the thing would not live below 2500-3000 rpm! I could not give it a big enough shot to make it work on the bottom end---BUT not enough stall in the converter to get there. Thats what I get for trying to bandaid a bad set-up. The plus side is what I learned on the tune side! I hate Carters!!!!!!

    Its a "spacer" of sorts to give it the look of a cross ram. But a cross ram actually has runners that put the car to one side or the other. When Offenhauser was pushing those, the Edelbrock Cross Ram was the rage. These things were being bought in pairs and put on dual quad dual plane manifold. Not exactly the same thing as a Cross Ram, and a huge HP killer. Destroyed the low end due to the increase in the volume, plus it destroyed the dual plane effect of the manifold because both sides of the manifold could "see" the carb, destroying the booster signal at low Rs, and the flow restriction and path way, plus disrupted entry into the manifold destroyed the top end. The thing was a loser all the way around and yet they sold shit loads of them.

    Dick Landy, Shirly Shahan, Butch Leal, Roger Lindamood, Dave Strickler and others ruled Super Stocks with crossed rammed 426 hemis. They work, but they take a lot of work to make them work. A tunnel ram is virtually a drop on power improver comparison.

    Agreed Bob, Dandy Dick Landy and Butch Leal were the two i saw make them work the best and there is another that the name you will know that ran them on the old Thunder Bolts but gave that up and went back to the high riser 427 in line 2 4 barrel deal. I also agree the sold a butt load only( I think ) because of looks, they really are a nightmare to tune and net sqwat in the bottom and top on a smaller inch engine under 9 k.

    It makes a great place to put the boat numbers. Just think how cool you were with one of those back in the day. Kind of like a roots blower. LOL
