340 the hard way; Stroked 318

I used a comp 280H cam in my 370 and it ran a high 13 leaving in 2nd gear with no posi and street tires. I think that that would get you close to what you are looking for. If not I would try to go up a little but no higher than a .510in lift cam if you are going to do much driving on the street with it. By the way that was with a stock slant six converter and it worked great.
