I've outlined several stroker combinations from mild to wild below based on budget and desired horsepower levels. To get maximum benefit from the stroker engine you need a free-flow intake with an S&B or K&N cone filter, 62mm bored HO throttle body, header, high-flow cat, performance muffler and 2.5" exhaust piping.
