Hi Sajeev,

Have a couple of questions: I have a 72 Dodge Dart that I am performing a 318 to 340 swap.  It’s taken longer than I planned (lack of time), I backed the car in the garage 2 years ago and now I am planning on firing it up in this April.  The question is the gas: I had about a half tank when I backed it in, and I put some Stabil in the tank, but I took the cap off to try a new cap and the tank smelled really awful.  I replaced the fuel filter, but should I drain the tank and refill with fresh gas, put some fresh gas in the tank to mix up what is in there, or pull the tank have it boiled out and refill.  I was driving the car up until March 2009, and I put that last half tank in there in March 2009.  I am in Long Island, NY so we have that crap gas till April.
