If you have the money I would go for it. The strokers improve the engine in everyway, more torque and more bhp across the rev range, lower down where you need it on a road car to. I've driven similar spec cars back to back on the road, one standard stroke and the other 3.4 and the difference in low down response was amazing,perfect for a road car. I really miss that low down torque my car had when it was 3.4, I'm just about to start building a new engine for mine with custom Mahle stroker pistons, Carrilo rods and BC crank actually. Wont be done untl next year though, just doing it on the side when I can.
