Hey Guys, just throwing this idea around.
What types of cams would you like to see in a 5.3L engine on an engine dyno?
I'd like to start the mild cam at 212 with a low .500 lift and I'm open for any suggestions for the most aggressive cam.
Any input guys?
thanks,
allen
i take it this is for baseline Horsepower increases? Great Idea. It would be nice to know what a paticular cam with a basic tune across the board can yield power wise. I smell a magazine article!
I'd like to see the same lift and duration with different LSAs. 112, 114, 116 and 118 LSA
Is it possible to start with something like the Z06 and work up, its like 204/218 or somethin in that area.
i'd like to see some dyno runs on a tsp220/220 581/581 112lsa
going to be my future cam for the 5.3 while i get the 408 built.. :smile:
how about the 212 218 low lift vs. 212 218 high lift, then the 220 220 114 vs. 220 220 112
then work up to the bigger cams 222 224 vs. 224 224 vs. 226 226
how about that lol.

tsp 220/220 .581/.581 and tsp 224/224 .581/.581 both on a 112
bluecajin and vv8s ideas are good, I want to see one in the 228 to see how much power is lost uner the curve
I like the idea. Should yield some good information no matter how you do it.
I would like to see you go into at least the mid-220s duration.
I also think the idea of comparing lsa, holding all other variables static, could be very useful.
xlr82sxs:
I have the cam you described in your post in a 92 with a 5.3/T56.
I really like it.
I would love to see those numbers. It will help me decide if I want to go with a more agressive cam.
Allen,
once u told me my cams where not of ur likeness cause they where too off of what u will recomend.....
How about trying mine in ur dyno
230/232 @ .050 .580/.580 @ 1.7 112 LS
Just throwing a curve ball in here Allen - Since most guys run a tight intake/exhaust duration (220/220, etc.), I'd like to see what a larger split duration would dyno at. A biased request obviously since I'm one of the few running that large of a split (218/228), but it would be nice to actually see numbers and have some real time proof of how a large split duration affects hp/torque. Futral said when running stock manifolds, the larger duration would actually help dispel the exhaust gasses and make up for the restrictive factory manifolds.

im puttin in the 220/581 @112 ill let you knwo how it feels :lol:

If your springs will handle it and I haven't sold it yet, I'd be willing to ship you my turbo grind cam so you can see how it works on that N/A 5.3L engine. The specs are in the for sale section.
how about doing this test on 6.0's as well i want a cam eventually, but idk what to get, i want a mild to moderate cam something that idles fairly rough but doesnt die, i want mac performance any suggestions here guys? links? sorry to jack the thread
im doingmy install tomorrow night on the cam so hopefully i can find my camera (since i lost it) and ill post up how it goes....

Thanks guys, I'll probably start with a 212 grind and end up with a mid 22x for the most radical. If time permits, we'll go as high as 230.
I like the idea of 112 vs 114. I think the power band will be very similar, however, the looser lsa will pick up on the topend just a bit. We may do that test as well. This comparison will probably be on a 220grind.
Keep'em coming.
thanks,
allen
mine is hte comp 216/220 .525 .532 on 114
Allen, I'm a little curious as to what will happen when I run the 110 cam I have. It was cheap, so I'll put it in and see what I get. Its a 228/232 .588 .595 110lsa. I think it may be a little big, but I am doing 4:10s and a 3200 Vigalante for a while until I get a big motor ready along with the turbo. I would love to have some heads done, but I want to see if I can be the fastest cam only LS based truck.

Ya, I'll start with the 5.3L, then move to the ls1 and 6.0L. There are far more 5.3's than ls1 engines.
I think that's a great cam, it should work out nice.

I am gonna go with the comp 212/218 high lift on a 115LSA,would be cool to see it on a 114 and 115 for comparos
Hey Allen,
I think you should run the one cam you recommended for my GTO. I think you said it was around 595/598 lift and the dur was like 232/234 on a 113. I know this is a big cam but it would be awesome to see just how much you can gain from a cam this size. :doh:
<div class='quotetop'>QUOTE(Yellowsierra @ Sep 14 2006, 11:51 PM) [snapback]65205[/snapback]</div>I will as soon as we get a 6.0L on the dyno.Quote:

I think that cam will give it 100hp.
Is there a cam that can give a 5.3 100hp? If so what kind of lope sound is it?
I guess my cam did that.....never felt the truck better, as for performance that is!!!!
Still have minor tech problems with the idle, but the exahust not and the romple sound R awsome
Any thoughts on a large split duration Allen?
<div class='quotetop'>QUOTE(DamnYankee @ Sep 15 2006, 07:43 PM) [snapback]65308[/snapback]</div>large split meaning 202/230? IMO, no need to, unless you're worried about emissions, maybe that will be a good comparison. I think a smaller split is better, but we'll find out.Quote:

thanks for the input guys.
<div class='quotetop'>QUOTE(farmtruc @ Sep 15 2006, 09:49 PM) [snapback]65314[/snapback]</div>That's why I was curious what kind of numbers you would see from a split similar to mine. It isn't a "popular" grind and the common belief is that the smaller split is the way to go. I'd just like to see some dyno numbers of a large split and same split cam in teh same setup.Quote:

<div class='quotetop'>QUOTE(farmtruc @ Sep 15 2006, 09:49 PM) [snapback]65314[/snapback]</div>I wasn't thinking that large. Most guys run pretty close durations (220/220 etc). Just curious what the actual numbers would be on some of the more common splits (218/228, 216/226 etc.). For example if you take mine, the intake duration (218) is smaller than the popular 220/220 cam, but the exhaust (228) is larger. So which one gets better numbers? I guess that's what I'm getting at.Quote:

VV8 was going with a 226/226, 585/585 on a 112. I would love to see those numbers, being that his old cam made around 50Hp.
Does anyone know if he ever put it in?

100hp w/ cam only and bolt-on's in a 5.3 is a very reachable goal in my book

compared to the old cam its a better down low cam, but the old one pulled alot better up top. just seat of pants meter and it don't work that great lol.
