    Default Porting an Edelbrock Vic Ram2...

    Thought I'd put up some pics of another Vic Ram2 I got in for porting.
    This is what we start with. Ugly doesn't begin...



    Notice the end wall above the runner...I'll fix that later.



    This is an earlier casting...must be an older intake. It's not near as rough as the newer ones, but still....



    The application is a 555ci NA engine in a flat, turning in the 7500+range. Some area correction was needed. This was just getting started.



    You can see the difference here, top to bottom...

    Remember that end wall?? I needed to get rid of that step and make the entry radius on that edge just a little more "friendly".



    This is everything in the plenum and the tops of the runners roughed in and sized...



    Runner exist are really ugly. Since I don't have the heads to match exactly, I didn't want to make them any bigger. All I could do here was straighten things out and "clean things up" as best I could.



    Much better.




    And the finished plenum.
    There you have it.

    Not intended to be a loaded question!
    I don't know if there will be any before and after dyno numbers on this one so it's hard to say. This was more than a clean up. The openings were pretty small for the engine and rpm. My guess is it could be worth 20hp or more.

    Steel, I'm curious, how much do you think the port being that tight to the wall effects flow to the #2 and #7 cylinders on an operating enigne?

    I have heard that polished like a mirror isn't what should be done to an intake runner! Is this correct for better atomization?

    I'm sure it's not good, which is why I try to at least correct that one side and at least give it a little more of an even radius like the other. Of course, there's not a lot of fuel coming from that direction either. I guess if a guy wants the most out of an intake, that's why he buys a sheet metal.

    Yes. I finish all my intake ports and runners with either 40g or 60g.

    Thats kind of what I was getting at. I was just wondering how much you thought it effected flow into the port only being able to feed from 3 sides.

    Wouldn't it help feed all the runners more equally if the carbs are mounted at an angle? say 45* or so.

    Holley twisted the carbs, and it didn't amount to spit. Its not a bad T ram. But no better than anything else built during that era, and certainly not up to a current Edelbrock, Dart, and almost any sheetmetal T ram. I would say it was any better than the Weiand Pro Ram of the time.
