Ok I have done some research and I think I have most of the mods planned out but not quite.

I was thinkin speed daddy headers with no cat no rear 02 and a cutout with stock catback.

auto lite 104s and 160 tstat

I already have a homemade intake

A PCM(not sure exactly which one)

Would this be enuf to run a 3.3 or even a 3.25 pulley?

About how much power would this setup make on the motor?

This is an 04 impala ss btw
 


Yea its highly unlikely you could get a 3.3 without some valvetrain work/intercooler.

You will need a custom in-car tune at that level.
 
ok well about how much power with that setup and a 3.4

also how much power with that setup plus the short stack and a 3.25 or 3.3?

Im sure these are some of the questions everybody gets tired of seeing but im new whole modding of l67s and what not.....you could ask me about a 5.0 mustang all day though.
 


Well when i get to that point im sure i will but right now i was just tryin to figure out what it would take to get to a certain power level.
 
Yes that thread is where I got the list of mods in the first post....I was just wondering about hp numbers and how much im gonna have to spend to get to where i want to be

Think 3.4, and that's with a really good tune.
 


probably not without a cam. also, leave your rear O2, your pcm uses that for fuel readings. although it's not as important as the first one, i'm sure it still makes a difference. i second the 180 thermostat and a 3.4". that'll put you around 270 give or take at the crank, getting close to 240 at the wheels
