I have a 2003 ecsb z71, It has a crappy Powerdyne, LS6 cam, exhaust, injectors and tune. We think it's gonna make around 400rwhp. Question is how fast should it be at that go level? Just want an idea of what to expect at the track. It has 3:73s also.

you'll be lucky if you brake 350. Im about 400AWHP with my mods. Stock trans and converter? I say you will run mid-low 14s

The Powerdyne is on 9#s and it also has a meth kit.

haha, OK you should see 400 no problem.
Are you running the stock trans?

For now, it's gonna get a Performabuilt.

So what kinda power you think it will make and what times. I know we are just guessing.

That style blower likes a looser converter than that... especially when you have a cam that will give you much more top end pull than stock. I'd go with something a little looser. Also, is it intercooled?

Do you have headers? Those would give you a huge bump in power with the blower.

I'd put you at a better time than a low 14 with the blower pushing 9# and a cam swap. I'll be generous and say 13.6 at about 105+ MPH. How is it off the line right now? I'm sure its not too bad, but it can't be good.

Converter/tranny and headers and thats a new animal though, we're talkin close to a second off that time.

Id steer clear of ptc.
They are junk on their lockup converters.

Im guessing you have a 5.3?
