What is the real world cost of a 331 stroker? What do I absolutely have to change? Can I get by with a Cobra intake until, I can afford a better one? What about heads, I have a ported set of 351's sitting on the shelf? I have to rebuild this winter and I might as well stroke if I can afford it. Can I just add pieces as money becomes available. My car is a 95' vert 5.0, T-5, exhaust,gears,K&N that I drive everyday during the summer.
