How much hp?

Just looking for everyones best guess as to how much power I'm putting down? Never have time to get on a dyno but my next upgrades will be an s&b filter, wicked wheel 2, and ported intake. Also tearing the top down to go with the hypermax non machining o-ring/headgasket kit. Truck was studded by the previous owner and he had them install black onyx gaskets. Hind sight is 20/20. What do ya'll think? I've been reading up on gearhead and vivians looney tunes. Thanks

You would be lucky to hit 400Hp at the rear wheels with most of the tunes floating around.

stock HP is what 325 at the flywheel?

Still running the stock tune? Then you are at the stock HP. Unless you are running more boost. But you won't do that without a tune.

So 325HP at the flywheel is what my guess is!

The K&N items aren't doing anything for you. Possibly more harm than good.
