Ly6 6.0

[87carl]

The LS7 has a little more lift too. I suspect it will work just fine, better than the stock 6.0 camshafts which have less lift. VVT is great but has its limits for high horsepower, high rpm applications. I know enough to be dangerous but am far from an expert on the matter. However, early on I spent considerable time investigating those stock camshafts and learned that they don't work in street trucks, even the vaunted LS6 camshaft gives up nearly 40 foot pounds of torque down low and you don't get it back until above 5,000 rpms which would only please kids and full time drag racers. It would kill a tow rig.

I was able to get lobe data at one time from Crane Cams and some others but have not found the info since they moved from Daytona to Mississippi somewhere.

From what I've seen they give up more on the low end with 5.3s but give up very little on 6.0 or 6.2s idk if that is due to better head flow or larger displacement or both so idk what it would do with the 6.0 with 243 heads.

How do you delete vvt if using a vvt cam like the l9h

To delete VVT physically, you remove the components and replace the front cover with one without it. The wiring can also be removed or just removed in the tune. A VVT cam can run in a non-VVT motor. In fact, many camshafts are ground with Gen III 3-bolt pattern and the VVT groove in the 2nd journal for oiling, doesn't hurt anything if not used.

That kinda what you're thinking?

That looks interesting for sure. Wish they would have listed some dyno numbers for what it improves and where at in the rpm spectrum.

The TPI intakes actually criss-crossed under the plenum, so the runners on the driverside of the plenum actually fed the passenger side head and vice-versa, making the runners like 24" long from plenum to the back of the intake valve.

I haven't found any that criss cross yet. And yeah I wish it had dyno results and better pictures.

I didn't know that everything I've read so far about deleting vvt said to change cam. That's interesting

Nope, don't have to. Now if you mean deleting AFM, yep, have to change the camshaft.

 

[Geotrash]

The cams you mentioned are for the rectangle port heads and would only work if I don't change heads.

Nope, the same cam will work great regardless of head port design. Roger has a cathedral port cam card for the same cam and it’s identical. He confirmed to me that it would be interchangeable between engines with cathedral or rectangular port heads and work just as well.

Wonder why alot of cams specify cathedral or rectangle port

 

[87carl]

I not against aftermarket cams I'm also looking into them just haven't found one I like alot yet. Basically the ly6 with 243 heads should be similar to a ls2. 6.0 with 243 heads so I have been looking for cams and dyno results for ls2 that's giving me somewhat better results. On the ls9 cam in ls2 threads I haven't found any dyno results for naturally aspirated. 90% of replies say there are better cam use this or that so it's hard to find the few replies from people who have actually put a ls9 cam in a naturally aspirated ls2. Everyone I have found that has done it says it drives and idles like a stock ls2 cam till you get on it and they liked it alot. I haven't found anyone who actually did it say it was bad. Only negative I found was a stock 5.3 with 243 heads guy said his was a dog off the line with the ls9 cam till they did intake and headers but otherwise he liked it alot. So idk why they other 90% say it will lose alot or would be terrible?

I haven't found anything for a l9h cam in a ls2 yet starting to look into that now

Am I correct in thinking this combo will be similar to a ls2? And when I get to the point of tuning can I tune it similar to trailblazer ss other than whatever cam

All of the cams I looked at were designed for LS truck engines, regardless of intake port design. Here's the one I ended up with and I'm happy with it. I pull a 6,500lb trailer so wanted something that would outperform stock and be a set-and-forget solution. It also has a fabulous lope at idle.

How's your dad doing? Were you able to get your truck up and running and get him home okay?

For aftermarket cams that's one that has interested me most. I got everything apart but haven't been able to put it back together been busy taking care of him and cleaning his house and built a railing and poured concrete where sidewalk was missing from doing well pipe years ago trying to make things easier for him so he can get around and do things himself when he recovers. I got him home last week and to an appointment on Friday in the purple dodge. Been using a couple step stools to get him up in definitely not a good solution but it works. The purple dodge has new shocks so it's softer then other dodge but he groans after every bump and dip. Hopefully today after I get firewood for him I'm hoping I can get to finally putting the burb back together. I gotta replace windshield in it before Thursday when it gets inspection and It gets it's annual undercoating Saturday. between those things dad's post hospital appointments and kids and wife's appointments next couple weeks are crazy so this afternoon is my only chance to get it done.

Summit racing has some great cam options at a lower price than most big-name guys. If all I wanted was a little more umpf out of a mostly stock motor with no plans of boost I'd seriously consider one of them. Or wait until a used cam with the specs you want pops up. I got my current cam used for $200 several years ago and had it in a different truck before this one.

Here is a decent option from summit

That 212/218 is fantastic and you won't be disappointed unless you want a crazy sounding cam which that will not be in a 6.0

I am hoping to have little to no lope want a mostly stock idle that's what has me against alot of the aftermarket cams I have looked into. I also want a flat torque curve not something that peaks and drops off fast.

If you want stock sounds, then the 111lsa on that BTr cam isn't what you want, the same duration but maybe a 113+ on the LSA would do a better job eliminating the chop. Has alot to do with valve overlap heres a good calculator to determine overlap. http://www.wallaceracing.com/overlap-calc.php

That's what I was thinking.

 

[Dantheman1540]

That's what I was thinking.

Long ago I was looking for a cam that sounded totally stock but added a nice bump in power across the board. I was specced 212/218 .600/.600 on a 118 LSA by texas speed. It was going in a 4.8 with a blower. I never did install it but it was hell trying to sell it, nobody wanted a quiet cam

Everyone wants the lope which is why most aftermarket cams are designed to lope. Not many are designed for smooth idle. Was that a custom ground cam or something off shelf from them?

It was custom, ended up trading it to a buddy who then sold it to a guy with a twin-turbo 4.8 in a Typhon. Never heard if he liked it or not.

A good tuner can take a lot of the lope out of a cam too

There aren't any good tuners near here that I know of was thinking either get hp tuners and try to do it myself or go through black bear idk yet on that
