It all depends on what you put in. A good set of forged manley rods, forged pistons, and a cobra crank will give you alot of room to play with. You can shoot a 300 shot if you want to as long as you have a good tune and all the nessesery fuel upgrades.

 

besides chargers and nitrous, what else is out there and how much gains would you get from them?

 

. . i already said. Power would be between 45 and 65 hp on an otherwise stock motor. THats a n/a power gain with just the motor. The only really reason to spend the money to get a stroker kit is if you're already rebuilding the motor and you want a little more for a blower.

 

That is some of the worst info ever! Their is no stroker block you just add a stroker crank with longer rods...and boring an aluminum block doesn't make it weaker...thats how you get them to be big bores.

 

oh man you are off again...strokers on stock 4.6's add almost nothing and its been proven!

 

I wish I could be of some help because I did have my 4.6 bored and stroked. But I have not had it dynoed and tuned yet. Besides I dropped the compression for boost later so for the time bieng that lowered the hp a little. Over all the car feels much faster but I boerd and stroked it to a 5.0 with all forged parts and had my heads ported and polished and put on comp cams all at the same time so it feels much faster but I cant say how much each one added separately.
