Straight 8 dual carb setup

Master Cylinder

I've been told the 320 benefits as the engine is so long it does not get gas to the front and rear cylinders like it should and the two carb set-up really helps distribute the fuel. I have an Edmond's dual carb intake manifiold I am going to use. A well respected engine builder told me I will really get better performance if I install headers. This is all on a stock 1950 Buick 320 engine. What do you have?

It is also pretty rare and thus valuable. I would certainly use it. On my 263 I made my own double intake with 2 inch SU's.

So being a complete noob to this car and Buick 8s, how do I tell what motor I have? Here is a pic of that helps? Thanks.

looks like a 263 , but check te other side. There is a small ventilation halfway the height. If it is in the rear , it is a 263. Iif it is in the front, it is a 320. Or see the references for engine identification.

Nice car! Seems an older rebuild ( do they still exist?). Looks like a 263 to me. Never seen a ventilation outlet like that. Maybe the rebuilder added that for extra suction. Best to check the numbers on the block (right hand side) for certainty. But clean and add the extra double headerset. It will also work on the 263. . see this: https://www.teambuick.com/reference/carburetor_2x2.php

Succes and keep us posted

High octane, that is a 1950 248 CI engine. The last photo one can see the crankcase ventilation inlet . See the cylinder walls? The 263 has a vertical rib on each one. This does not, therefore, a 248.
