If you need to rebuild you motor then it would be a good time to make it a stroker otherwise you should just run the stock motor, it should take quite a bit of abuse before you need to upgrade anything in the shortblock. The stroker kit increases bore size and stroke to increase displacement. I'd go with an intercooled blower setup, having the lower air charge temp the less likely you'll have detonation problems and you'll be able to run more boost on pump gas with the intercooler. The Procharger kit comes with an intercooler. You could make 500 rwhp with the right tune on the stock motor with a blower and that would give you enough power to run mid to low 11's. You might need to upgrade your clutch at that time too, I don't think the stock clutch would last too long at that power level. And if you're going to put slicks on it you're gonna want to get 31 spline axles and while you're working on the rear, I'd put a set of 4.10 gears in it. Have fun.
