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.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?
