alright here's my issue. I've searched for cam only 5.3L resutls forever and i'm mainly finding results and OP for cammed 5.7's. i blew the motor in my 01SS and i'm replacing it with a 5.3L from a 2001 silverado. Mods:

LS6 intake
LS6 TB
LT headers
3200 stall(looking to upgrade to a 3500)
4.10 gears
UD pulley
Ported Heads
150hp n2o(turbo set-up in the making)

car will be driven somewhat daily and will see a LOT of street action and some track action a few times out of the month. something in the 23x/23x was ideal for the 5.7 but how would this compare to the 5.3. i've been looking @ something close to 228/232 for the 5.3 but i've also notice some pretty decent numbers/times from some of you guys running 22x/22x w/ just a cam. i'm sure being that i'll be running a lighter vehicle and flowing more air with the ls6 i/tb that i'll be able to get away with a bigger cam but i dont want to put one it that's TOO big and i have to run a stall of around 4k. a 3500 would be fine but really dont want to be any bigger than that simply for driveablity puroposes

 

what vehicle are you putting this in?

 

2001 Camaro SS

 

When mine had just a cam longtubes and a mail-order order tune it dynoed 341rwhp, no clue what it does now, with head and intake on it, but last time on the dyno it hit 440 rwhp on a 100 shot ,but had a nitrous backfire at 4800 rpms before i could hit the other 100. Oh and my cam is a 224/230 .581/.588 112lsa

any others willing to post up some numbers

 

I been thinkin on calling Texas Speed and asking them about a cam for a 5.3. I've been wondering what the biggest cam that can go into a 5.3 with extensive head work (going into an old Monte Carlo) but yielded little results.

I hear the TR220 is a very streetable cam, and I believe it's the 224/231 (?) that people have been calling good, but I think like me, you're looking for more. Good luck and if you find something out please let me know.

 

will be sure to do so, i've seen some good #'s with the 224/231 but i'm still considering going a little bigger like 228/232 atleast. The suspension on my car works damn good on the street so i really want a motor that will utilize it.

 

You're gonna have to let me know how that thing turns out too

 

dunno if you're running n2o or how much but i'm going to try a 232/242 .580/.590 116lsa and see how it works, a lil bigger stall and prob bump up to a 200hp pill on a progressive kit
