LSX 376 what kind of power

[Blown90Z]

I am getting really close to finishing my 90 iroc convertible lsx376 swap. Should be done in a couple months. What kind of power should i receive when the car is tuned and done. Here is the specs: Lsx376 crate engine, Ls3 intake, Nick williams 92mm throttle body, 2" stainless works headers,cat delete, slp underdrive pulley 25%, aeromotive a1000 regulator, 411 ecm, 700r4 auto built for the 9's and 4thgen 10 bolt with 3.42 gears. I know gm rates the stock lsx 376 motor at 450hp. Reason i bought this motor it was cheap at 4k for it and it is great for my procharger down the road. Anyways here are some pics of my current setup.

Not sure of the power, but man does that look good. I want to put one of those in a '50 pickup and use it as my tow truck.

I recently dyno tuned an LS3 480 HP crate motor with a manual transmission in a Porsche.

It put 443 to the ground.

I expect you will see around 400 At the wheels with the Auto if you can lock the converter during the dyno session.

Ya was hoping for around 400 to the wheels considering since i have longtubes and it will have a cold air intake. I do want to change the cam later and i do have a procharger just need the brackets,but i want to run all motor for a little while. Well ya hopefully i can finish my project early than a few months.
