I have a 1972 Pontiac Lemans with an 350 and Two Barrel Carb. 160hp.
Three speed automatic transmission.
We are the second owner and the engine and the transmission, carb, etc
are all origional parts minus the alternator and radiator. Oh well...
I also have an single exhaust. (ow that hurts) I'm going to put
another header muffler and tail pipe to have duel exhause within the
next month. I am also looking for a Vacuum Switch? (I have heard it called a 
million things. (Thermeo vacuum valve, etc) I attachets to the carb and the 
carbon canister. If you know where I can get on please inform me.
What other things can I do to this engine to get all the performance out of 
it? Four Barrell Carb? Is it worth it? Anyone have a 400 or 455 GM engine for 
the year 1972?
