Default Horsepower?

So I was wondering what kind of numbers I might be pushing at the flywheel.
Lets see, I have the Intense fenderwell intake kit and magnaflow mufflers on and I'm running good synthetic oil. I would think that those 3 things would bring me up 8-10 horses and I have no clue about the torque. I ordered the 180 stat(I wont notice the difference with and without it other than different readings on the temp gauge.) By the holiday season I'll get that aeroforce gauge and a few pullies and experiment a little with those. I figure a 3.4 will give me 10 ponies and a 3.5 maybe 8, so that could set me at 255-260 ponies.

But thats all just my guess, I'd like to know some more solid figures from people that know if you guys don't mind helping me out. Much thanks for any input.

I'd say close to 270. L67s are underrated by GM and most dyno 250ish stock. Torque is often over 300.

pretty sure a 3.4 is good for more than 10hp

A 3.4 will give you over a 20HP gain IIRC with the proper supporing mods to prevent KR.

what are the proper supporting mods other than a custom intake and hi flow mufflers?

all cars are different, thats why a scan tool is needed to make sure you dont have any knock retard... with your mods, its probably safe to say you are ok
