5.3 best cam choice hi im swapping in a 02 5.3 into my 89 camaro. i was wondering what the best cam for the 5.3s is. ive done searches and there is alot of info. my setup is a ls1 intake for now manifolds possibly long tubes, 3000 stalled built 700r4 3.73 gears. any info i will be thankfull.
I've kind of been out of the loop for a little bit since I have no LSx vehicle, but I'm looking at picking up a 5.3 for a project of mine like you are.
Since both engines have the same stroke, if you have a hot cam for a LS1, it should work just fine in the 5.3. However, since the engine is smaller, a cam that might not seem big on a LS1 will be more noticeable in a 5.3. I'm not sure what your goals is, but I wouldn't go too crazy on the duration (but that's just me). My engine will be going in a truck, so I'll probably go with the Lingenfelter GT2-3, better than stock, and the smog guys won't notice. The stall and the gears will help out a lot if you choose a cam that's pretty lumpy. Good luck.

I have a 5.3l with a 222/222 .566/.566 112lsa, it feels stock-ish on the low end, mid range is better and top end is great, good sounding idle. It would be a nice cam for a car. Through a TH-350 it makes 331 rwhp at 6000-6200 and 315 rwtq about 4000-4400. I bought is from LPE, I think the part # is gt2-5. I am currently going to a 408 stroker to get a better low and mid range becuase this is in a truck.
224/224 .581/.581 114
218/224 .566/.581 112+4
224/228 .581/.588 112+2
These three have all had really strong performances that I've seen in the dyno section for 5.3s. I am planning a 5.3 swap for my truck (s-10) and I am leaning towards the 218/224 combo.
