VHP 228/232 .551 112 LSA could i run this cam in my 5.3l? assuming a 3000 stall and tuning options? i dont think it would be too big, recommended rpm range is 2700-6500, could i really spin my motor to 6500 with no problems? i understand that i should invest in some comp 918's with this even though lift is an acceptable .551...

if thats too big what about this...VHP 220/224 .551 114 LSA (2700-6500)

The 228/232 is what ima be going with when I do my 6.0 swap, wouldn't recommend it on the 5.3 though since its a smaller engine, maybe a 224/224 cam should do well

Well, lets say it actually pulled to 6500 as advertised (which it may). You are gonna shift around 6600-6700 to get the full range. I wouldn't spin MY motor up to 6700 without upgrading rod bolts. Actually mine are upgraded and I only spin to 6200. They are cheap insurance. Other than that I don't think that cam is TOO big but it depends on how drivable you want it to be.

VHP told me not to even put their 220/224 in a 5.3. They siad that it would not idle well.

The rpm range of that cam is for the bigger cubed LS1. After putting it in the 5.3, the range would probably be somewere in the 3000-6800 range. Below that it would be a turd. Bigger isn't always better. Everybody seems to like the 210/218 cams from VHP in the 5.3s. Just my .02

Vinci would most likely recommend their 210/218 -- Both Joe and Roger have told me that they get the best all around power out of those cams. The wisdom is to sacrifice some upper rpm hp for all around torque and drivability.

well see what im looking for is something that will run fast with a stall, city driving i dont really mind it beig a turd and i dont need a bottom in torque monster and i'd like to put up some good dyno numbers...how bad is dont idle well though? cuz all cams dont idle well any ways though i understand the 228/232 would be a little big and the rpm range would be shifted due to the smaller ci. right now i have a 204/218 LS6 cam and im basically looking for something that will give me MORE POWER, as time the tool man would say

so the 210/218 .551 114 LSA would be good?
what about the 216/224 .551 115 LSA...i understand bigger isnt better just checking out my options

also what kind of upgraded internals would i need with one of these cams...comp 918's? pushrods? lifters? i should need too much because the lift is within stock head range at .551 right?

I can't tell you what they meant about "won't idle well", but I barely mentioned that cam before they said they wouldn't recommend it in a 5.3. I think my 210/218 on a 112 LSA idles pretty well at 600 rpm.

If you want to run a VHP cam, I would run their dual springs since they are meant to go together. Hardened pushrods are a cheap and easy upgrade. The stock lifters are fine.

I dont think the cam is too big. You may want a little more converter, but I put a 226/226 in a 5.3 ex cab last week and it is just plain bad ***.

Just noticed your sig... If you're moving to a turbo you want a different cam altogether. You want an intake bias with a wider lsa to make the best power from the turbo -- that means you give up some of the idle lope, but make a little better vacuum and will idle somewhat better. If that's the case, I'd wait on getting the turbo and then cam it.

If the STS is a long ways off, and keeping in mind your current cam and goal of more power, I'd suggest something like a 216/220 or 220/224 on a 112lsa (and this will be not optimal for the turbo). To do something that will work now and for the turbo, do a 224/224 on a 113-114lsa
