Has anyone on here made 400+rwhp on motor with a 5.3 in a Silverado? Looking to see who has gotten serious with a completely streetable H/C setup. Thanks for your help.

 

the highest i know of on a 5.3 n/a is bluecajun5.3 with 330rwhp and runs 12.53, not sure wht v8 dyno'd but he runs a 12.51

 

But from what I understand, his is cam-only, correct?

 

I can't think of anyone who has done h/c on a 5.3 but many of us have done full bolt-ons with cam.

 

02reaper use to run a h/c 5.3 but i can't recall the #'s it put down off the top of my head.

 

I'd be suprised if anyone hits 400+ on a streetable n/a 5.3.
Most of us are struggling to do it with 6 liter's.

 

It would take a complete Head/Cam/Intake deal... You know, all of the i's dotted and T's crossed for sure. I don't think I would of even thought it possible until I saw Cajun put out 340rwhp with his 220 cam, SAE corrected, converter unlocked.

 

I just got through helping a guy do a dart head, 224/228 110 cam LS6 intake EWP and full bolt ons. Everything you can do to wring out any extra power has been done. It will hit the dyno on the 9th. Its a 4wd though...

 

Good lord that's a large cam for a 5.3. Hope he has a stall.

 

3200 brakestall, it will flash a bit higher
