    Sideways mounted carbs

     



    On a street car with a tunnel ram is there a difference between inline or sideways mounted carbs? Some magazine articles state sideways vac sec carbs can lean out one bank, but if the carbs are tuned right I don't see how. The runners enter the plenem in a square pattern so turning the carb 90 deg shouldn't matter. If you do get lean cylinders does the motor care what pattern they are in?

    I never thought enough of tunnel ram intakes on the street to try any experiments with one, so don't know.

    I do remember seeing that on an inline six and using a 4-bbl intake, the carb should be turned sideways to prevent leaning out of the rear cylinders.

    I'm running a Weiand tunnel ram w/ dual 450 vac sec Holleys on a 406 sbc. The carbs have been converted to center hung bowls and a metering block on the secondary side so I have them turned sideways. I had a Victor jr. w/ 700 dp before and the tunnel ram has more torque everywhere. I guess the older rams were designed for a 327 so a 406 tames it down some. No choke makes it a little cold blooded but when it's warmed up it has excellent street manners.

    I've seen several blowers using the "sidesaddle" mounting. Not quite the same as the fuel enters under pressure, but linkage is available as are fuel line kits..

    Holley makes a kit for sideways mounted 4150 for boats..

    It would be a little difficult to mount large bowl carbs inline....

    i always use carters(edlebrock) for 2x4 intakes. and on my 428 ford i had them mounted backwards worked great. on my y-block i had holleys one mounted with the primary to the drivers and the other to the passenger side. worked good was running a tunnel ram which i made myself.
