Need dyno 206/212 .515/.522 112LSA in a 5.3
 

hey guys i'm looking at cams right now. Between comps 54-408-11 (206/212 .515/.522 112LSA) and the 54-412-11 (212/218 .522/.529)

Right now i think i'm leaning towards the 54-408-11 but i can't seem to find anyone who has run it. I want to see some dyno results and hear what people think about it.

for the 54-412-11 i found this https://www.performancetrucks.net/fo...d.php?t=435536
which is a great review of the cam but i want to see something like this for the 54-412-11

I really like the gains NicD saw on the topend but i spend most of my time below 3000 rpm. i want to gain bug on the low end from 1000-2500 rpm area but not give anything up on top.

right now i have truck manifolds without cats and might be moving to longtubes in the future.

what do you guys think about these cams, help me decide

Go with the 212/218, in a 5.3 it has a tendency to gain power everywhere.

You really need to get some long tube headers with that cam as you will probably only see about half the cams potential on stock manifolds. Plus get a custom tune / retune it since you have efilive.

X2.

i vote for the 212/218 as well, and def with a set of longtubes to go with it.

I've been running the 206/212 on a 114 in my dd for over 7 years now, and it was worth some good gains over stock, even on the stock converter. When I was on 33's, I swapped in the cam and had the PCM tuned for it, and went from 16.5@81.7mph to 15.6@89.5mph in the 1/4 mile. Not bad for a cam that absolutely everybody will tell you is too small. Even this baby cam can benefit from a higher stalled torque converter though, but it isn't necessary. I like my truck much more since I installed my FLT Level7 65E trans and Circle-D 3k converter. If I had to do it over again though, I'd probably go for the tried and true 212/218, probably just because I've had the 206/212 so long that I'd like something different. Actually, if I had the dough, I'd like to slap a TR220-112 in my 5.3 to hold me over until I can afford to put my LQ9 together :D

Also, FWIW, my fuel economy got better by about .5 mpg after the cam swap, if I can keep my foot out of it :lol:

Ur not going to find people dynoing such a baby cam. I ran 206/212 in my old 4.8 with longtubes,2600 converter, and 33s. It ran great for what it was. On a 5.3 I would definately do a 212/218 with some ls6 spring.

Thanks guys for the responces, it was just the push I needed to choose

I am looking at the 212/218 high lift for my lq4

I'd look bigger than that for a 6.0. Something like a 22x/22x @ .550/.550 - .590/.590

I like my gt2-3 cam in my lq4, I'm not convinced the big cams really gain all that much on a mild setup. Part throttle power is awesome. Yes bigger cams gain up top but you need power down low when you're cruising along in 4th with the tc locked. I can go up pretty much any hill with the tc locked and my tight converter makes for a great driving combo.
