Yes, baking soda will help... try soaking them in a solution of baking soda and water for abut 6 hours... fill your tub 1/2 way and pour the entire contents of a small box of baking soda... stir it up a bit and wait about 6 hours or longer !
My most favorite was the 1972 Olds 442 I had as a teenager... I have one of the first '08 SRT Challengers... it's almost a year old now, but somehow not as fun as the 442 was !
