The 305/3-3/4" stroker crank deal was an invention to get the CA boys and their Camaros, etc. around the smog police more than anything. It'll increase the torque, though- but the cost is significantly more than what you need to spend to reach your goal of 250-300 hp. Put another way, I'd rather use a mini blower (that could be used on a 350 later) than I would a stroker crank.
