thats my current goal

 

They're have been a couple nnbs trucks hit 400 rwhp but I have yet to see an nbs do it yet with a 5.3 that is

 

But what do you know? Your only doing 12.4 N/A and 11.74 on a 75 shot and have been on here gaining knowledge on how to set these engines up for over 4 years?
You Rookie You should run this cam, you'd be in the 9's by now

 

You wanted dyno numbers so here you go. Keep in mind, these are engines with more cubes so they are going to make more hp than a 5.3. To get the 5.3 in these ranges you will need a F A S T intake and headwork.

u right, i rest my case. i try to point people in the right direction, i'm not all out just for my own...

 

Should be shifting around 66-6800, thats what i shift at with my V3

 

well all I can say is your not going to run better at the track, but on the street it should run pretty good with the m6 compared to an auto, scott work on your base running airflow to get it to idle better, I know mine would of ran better with a new converter but hey bluecajun5.3's truck runs pretty good for what it has done to it.

Dyno is for tuning purpose only and dyno queens, like lance I only put down 330hp and tq ahaahaa

 

It will prolly run great on the street and sound badass. Scotts truck hasnt improved on the track, but runs great on the street, especially up top, and it sounds fuggin awesome.

 

i have no running issuedswith my 228R cam in an auto what-so-ever. mine put down 351rwhp/338rwtq SAE with mod in sig, on a dynojet, though i personally think they are a bit inflated. i'm thinking more around 330/300 judging from track time etc.

 

If your truck was a drive by cable, I'd ask to see parts of your tune. Mine needs alot of work
