Most stroker kits add power. As to how much I am not sure, especially with the lower compression. A 4.0 to 4.3 kit "is supposed to add" 30 hp and 30 tq, but I am sure that is a pure N/A build. I would say around 40hp and torque more or less, but I have been wrong before.

I do know that it will probably run better because everything is brand new. No wear and tear if you know what I mean.

Get it DYNOed!!!

I don't plan to get it dynoed for awhile. To be honest, I'm expecting almost a 5% loss in power.
