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.

The cam depends on what kinda power you wanna make.

tsp224 works really well with the 5.3

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.

thanks for the suggestions, im looking for around 400 hp and trq. ive been thinking of doing car crafts oct 04 build of a 5.3, consist of stock 5.3 long tube headers, lpe gt1-1 cam 229/242 .631/.631 and 114.5 lobe sep., comp cams behive springs lpe steel rocker stand 30lb injectors. with a truck intake, they made 369 trq. at 4800 and 413hp at 6600. im just wondering if anyone has done a similiar build and if so what is the drivability like.. i drive my car alot but i beat on it alot too so i need a motor that will perform, my current motor is a copy of a car craft build supose to be 401hp and 427 trq. its carburated and i want fuel injection. my current setup i run out of motor at about 1000ft on the dragstrip and have to shift into overdrive and thats at 5400rpm. i have a 5.3 in my seirra and i love how it revs all the way to 6k. thaks again

do you need to do anything to the 5.3 for this cam or can the engine be stock?

Wow, really old thread. To sum it up, LS engines are a blank canvas. Have fun.
