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.

sideways i always heard was better for drag racing straight was better for street. but im not 100% sure

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.
