Default HP guesses?

It’s going to be till the end of the year before I get my truck on a dyno so any guesses on power number?

Stock 4.8 with a Tvs1900, 2.8 pulley seeing 13-14psi, long tubes, LS2 throttle body and running 91. Tuned by Atomic.

Depends tire weight, cam, meth inj etc. Right setup could go 500's pretty easy id think.

As of now it’s got a stock cam no meth and pretty heavy tires (BFG KO2 285/70/17s). Not sure if I want to cam the 4.8 or buy a 6.0 to start building. Also going to start looking for some cheap take off wheels and lighter tires to play around with.

Sounds like a nice little setup. Ive wondered about putting a 1900 on my 02. Never done a blower setup and curious how fun itd be compared to the turbo just for putting around big D

I love how snappy and linear the power is. Should help a lot when towing and climbing hills off road.

Kinda debating ether building the 4.8 a bit maybe heads and cam or just going straight to a 6.0.

That’s true I may never dyno it. Numbers aren’t that important to me, however I would like to run it at a track sometime when weather gets cooler.
