Ok so I was gonna go with Allen's new kit, but the trucks a DD and honestly I can't afford to find all the weak links to have a reliable 500 horse DD. So plan B: Cam and bolt on 5.3
Leaning towards a GMPP cam, because I get a really good price on them so the Hotcam is a little small so I think I've settled on the Stage 2 Hotcam specs are:
227/239 @ .050
551/551
108 LSA
Here's a video clip YouTube - gm performance parts stage 2 hot cam
So my question is, is it too much for a DD?
Wow...that LSA is huge. Not sure if that would bug me as a daily driver or not. I tend to think it would.
Try one of these cams.

Moze I think you're right, I'm just thinking with my wallet. Even the Hotcam is on a 110 I think, not too DD truck friendly, but they sound very good.
Wish I could make up my mind keep flip flopping back and forth, you guys suck had I never joined this site I never would've got into this mess.
Larry, just so you know, that's blower surge not a huge cam.
Dont think with your wallet or you'll never get anything done. Do things right the first time and get a custom cam.Quote:

Do the front mount, your going to have to do all the supporting mods anyway. Why half step it?
Probably will now that I think about it, so I guess I can rock a stock LS6 cam and manifolds for now, chances are that'll blow the 3500 to smitherines anyway (or not, I've seen Dakotas pushing 500+ through them)
Chick's 3500 is holding fine with his cammed 5.3Quote:

The converter actually made it tougher to drive as there was less load on the engine at low RPM. I was able to tune the truck great with just the cam and a 3000 torque converter, but when I swapped to the ss3600 it made it much harder to get it to idle.
If I could do it over I would have gone with a tr220. I don't think people are running any better times with bigger cams in a 5.3L without dropping serious money on heads, intake, etc.
BlueCajun has run some amazing times with the tr220.
Bought the one thunder550 had for sale
220/222-580/580-114 cam, comp XE-R lobes
Congrats!! I was actually about to tell u to look at that one!!
that stage IIhotcam would be like an ls2 cam on roids! holy cow, yeah, you picked a great cam
Wanted one that would work well with and without boost, seen that one in the Classifieds and jumped on it.
I know you already bought your cam and it looks a good choice, but just to shed some light on the came you had picked out. Not too terribly big. I'm running a g5x3 in my 5.3 of course I have some nice heads but..I've also run a 232/236 .600 112lsa in a bonestock 5.3. Your daily drivabilty is all in your tune.
I drove the 232/236 with a stock converter and cut the same 60' as I did with my smaller cams and also got 20+mpg.
I now have the g5x3 (236/240 .615 112lsa) with an edge 3800 9.5" converter and it's very docile around town. No surging, no annoyances. But I have a badass tuner. Drivability is all in your tune
