408 budget stroker ?

Im building a magnum 360 for my 67 dart in my research I came across an article or 2 on the ease of making my engine a stroker . Besides the crank and the harmonic balancer what do I need. Read a little that the stock rods will work and I do need to change the pistons. Im on a small budget but if I can rake in almost 50 ci and 75+ lbs for 600 win win. Bit im uneducated on the whole deal.
