    I am debating. I have a chance to pick a 360 tunnel ram on a parts trade. I have always wanted to run dual quads sticking out to the hood. :toothy7: My 360 is done as soon as I pick up my heads from the machine shop. I planned on running a Eddy RPM and a 750 that I already have, but this might be too tempting. What carbs would you guys recommend? How would the street manners be? This will be a weekend cruiser and make the occasional trip to the track.

    Here is my combo

    Zero deck 360 shooting for 10:1 CR
    KB107 .030" over
    Stock rods and crank
    Comp XE275HL
    J heads 2.02 1.60 (mild porting and bowl blending by my engine builder)
    1.6 roller rockers

    904 with TF-2 and 3K stall convertor
    3.91 gears with detroit locker

    This is what it would be going into.

      Depends on which tunnel ram.

      340 8bbl is pretty sharp on getting a TR to run on the street. Just takes time sorting them out.

      Even though i'm not an eddy fan, I think a pair of 500s would work good once dialed in.

      I sure enjoy my 340 with 2 600 vac. secondary holleys on eddy street tunnel ram. I will have to give crackedback a ride so he can give his opinion.

      I always wanted to do a tunnel ram on the street, but with 2 throttle bodies and multi port injection.

      I've had an Eddy Street Tunnel Ram on the street since 2005

      DSC_2805.jpg

      The smaller plenum helps a ton with a street car - the larger the plenum, the less velocity you have at lower rpm's

      My Combo :

      360 - std bore
      kb 107's for a 9.4:1 comp ratio
      stock 1978 small valve heads ( with air injection ports taped and plugged)
      mopar p4452992 cam ( 474 lift 280 adv duration ( 230 ish)
      stamped rockers
      904
      dynamic 9.5" converter
      3.23 gears

      The car has over 8000 miles on the street / strip with the setup - I've driven it in the rain( with a cover over the scoop )

      never had any issues !

      I started out buying the holley 450's - once i got them out of the box I returned them!
      They had a mechanical secondary but no accelerator pump for them, it seemed like it was goung to be bog city - and in talking over the years with others who went that route, it in fact was a PIA with the design.

      I rent with a set of holley 390's ( vac secondary setup)
      DSCN4399.jpg

      I needed a holley balance tube to connect the secondary canisters together, to make them open at the same time :

      DSCN4394.jpg

      My best pass was a 1.74 60' - 12.56 best ET, and 108 best mph.

      with a ported 4 bbl intake and a holley 780 the best it would do was 1.84 60' - 13.20 @102

      the T-ram made power everywhere for my setup.
      I can get 16 mpg with the setup as long as I took it easy...lol


      Last year I went with a pair of EZ EFI dual throttle bodies :

      DSC_8651.jpg

      Talk about sweet! I gained 21 hp on the dyno, and have all the benifits of a modern efi system

      Here is a before and after vid of the car running with the carbs and efi :

        That looks and sounds awesome.

        I don't known thou, I think you should had played around more with the carbs. Carbs make more hp, they respond better to a/f ratio changes over f.i.

        I know, 80% of folks think f.i is better but not 100%

        carbs get a ram effect, that is were they can out hp a f.i. Those 390 carbs are very small, how much cfm is the f.i. units?

        the efi units are 1000 CFM a piece - my take on it is that the carbs were my bottle neck, but awesome for the street - the EFI units are the nest of both worlds - more hp from teh added CFM and no off idle issues like a set of large carbs would have.

          Dodgefreak- Nice!

          How do you have the o2 sensors?

          I thought about adapting a crossfire style 2 TBI setup and having the 02 for one in one header and one in the other.

          I know that's cheating because one side would tune one throttle body/injector set, but the factory let one side tune the whole system a lot of times.

          Did you ever end up putting this combo together? I have a very similar build in mind and an edelbrock TR1Y sitting on the shelf
