Ok to start off I am a mussel car guy (68,70,72 cutlass 442 my girls) but my wife fell in love with this 1950 Buick special so I bought it. Well needless to say if there is not a V in front of my 8 I am lost. So would any one care to ancer some questions for me? First what is the glass jar on the firewall for? It has some kind of oil in it and runs in to the intake below the carb. 2. What is with the switch on the carb and can I by pas it and if I can how. And 3 will a V8 mount to the existing frame.
