    where to find those tunnel ram carb spacers that have a "cone"
    that extends down into the plenum, so it drives better? cant seem
    to find them, apparently my google-fu sucks tonight... thanks!

    search for "anti-reversion" carb spacers.

      thanks squirrel-the ones im thinking of take all 4 barrels and funnel them into 2 basically,
      right over the center of the 1/3 and 2/4 ports on the front carb, and over the center of the
      5/7 and 6/8 ports on the rear (on a chevy motor), and extend down into the plenum 3-4 inches.

      like a vertical metal duck bill grafted to the bottom of a spacer, for lack of a better description.

        Are they old or recent?

          saw them as recently as 3-4 years ago on the www, just cant seem to pull em up now.
          i do realize TONS of things chage in 3-4 years, however. maybe they went extinct....

            cant find anything either, this is interesting to me since I got this Victor Jr we were going to try. The guy cut off the bottom oil galley part to do some welding inside that kind of sounds like it has the idea you are speaking of.

              this sounds like a maybe, but no pictures, just possibly more search clues. http://www.freepatentsonline.com/8733312.html

              edit, there is a PDF file that will open if you open it with a pdf viewer with sketches.

                  thats REALLY close--same thing except the ones im looking for
                  the carb flange was maybe 1/4 thick and the rest fit down inside
                  the existing plenum. these look like they replace the entire upper
                  with their design, sorta like this one.....

                  https://www.realstreetram.com/

                  again, close but not quite what im thinking of. but thanks for
                  searching for me!

                    I thought that almost crossover "H" pipe tying the two banks together was interesting on the patent. The first link had a dodge pro stock manifold with more of what the guy did to this one. I was just looking for an easier way to get to a Sniper fabricated manifold so thought we could just cut out most of the plenum to put our "tank" on since it was really hard to start from scratch. So I dont know if this guys ideas were for more top end or bottom end since most of these "performance" manifolds have rpm ranges starting over 2500 and just make them not likely to want to work on the street.

                      If you look through the patent application info and the PDF's, the links Anotheridiot and Squirrel posted are for the same thing, and the same guy, Wayne Kever of Ft Collins, Colorado....the same place RealStreetRams is located. Sounds like it's the same guy.
                      I think when he first put this idea in motion and got magazine coverage they offered the insert/spacer deal you are thinking of, along with just the top half T-Ram castings they currently use as separate pieces to anyone with a tunnel ram, but quickly went to just offering the entire package they sell now..
                      You might try calling them and asking about it.

                      Interesting that the first item in the "U.S. Patent References" list is the patent for Jim McFarland's Tork-Link manifold.

                      The Real Street Ram is what came to my mind when I saw this thread.

                        the ones im thinking of looked like the reed cage on a 2 stroke dirtbike,
                        only they are fixed-no moveable reeds. im guessing they went extinct,
                        much like the big block chevy "torque plate" exhaust inserts, as i havent
                        been able to find anything on them.

                        might be time to bust out the welder and a couple of the thin gold zinc
                        steel spread-to-square bore edelbrock adapter plates and some sheet
                        steel and make a pair, my younger brother is determined to run a tunnel
                        ram on the street and im sure they would help with both fuel distribution
                        and velocity for better street manners.....

                          It might be worth a look at the restrictors that folks use to reduce the ports in Ford Cleveland 4V heads. They tend to be WAY RPM happy and these are said to help. I haven't looked for them lately but they might be more or less what you're looking for.

                            I will say this...since this is Bangshift man, come on!!!!...that Real Street Ram crap is for the street rodder wanna-bee's to putt-putt around the cruise night with a tunnel ram....IMO anyone really running a tunnel ram needs to really be using it - not caring how it acts below3000 rpm, running a 3000+ rpm stall converter or a manual trans, revving it to 7500+ rpm and making serious noise and power with it....otherwise, why bother??.

                            I'd think you would be better off to get carbs with annular boosters so it can be tuned to still have decent manners at 2500 rpm if you have to have it....choking the tunnel ram off with little funnel gimmicks under the carbs is just stoooopid IMO.

                            I had to say it....

                            Oh well, different strokes for different folks, a butt for every seat...

                              Thats the problem, all city driving is below 2500, so you just start to get decent at 2500 you still have a problem. Some of us have to drive thru a city to get to a highway.
