I've found that "stroker" and "budget" don't go together. All the little parts and machine work adds up quickly. My stroker is probably going to get me for about $5,000 just for the LONGBLOCK! If you are trying to do one on the cheap, don't. You'll end up making as much power as you would with just a good H/C/I 302. Look at the numbers Jake made with his for example. If all you want to do is run with a Cobra, do H/C/I and throw on some nitrous. With even only a 100HP shot you should be able to edge by one.
