Spec me a cam 06 LQ9 4x4 ECSB
I just want a cam with to increase mileage on highway or at least keep it close to stock mpg and some chop at idle that's noticeable, this is my DD, but I want to have some fun at track on occasion.
I have some Kooks LTs 1 7/8, Kooks Y pipe, 3" electric cutout,corsa touring muffler, EFI Live tuned once I get cam in. And a SLP 160 Stat.
Did the Airaid filter and Tube to stock box.
The trans is a 4L70e, I plan to get a Circle D 278mm 3000 or a Yank TTS 3000.
Truck has 70K miles, so I will do both servos, and Transgo Kit with TC at install. Also, bought a Tru Cool 40K cooler to keep temps down.
The factory gears are 4.10s front/rear. Stock tire size(265/70/17), but plan on going to a 285/70/17 for less rpms on highway for mpg. (32.8in)
I tow a double axle trailer on occasion for work and a 27 FT CC boat on some weekends to ramp. Use the 4x4 when I go hunting to get to the camp, or at the track.
I have used the search button, but theirs some many options on cams, I'm trying to narrow it down with people's cam they use in the same application.
I'm thinking a:
1. 224/228
2. 224/226
3. TR224 114 LSA
4. 228/228 .588/.588 on 112 LSA
5. 212/218
6. 216/220 561/.581 lift 113 LSA
7. 220/112
8. 232/236 .585 lift on a 112 LSA
9. Your cam and advice?
Thanks for the help. I have no experience with cams, just FYI.

220/224 on a 112 LSA.
I think I'm about the only one that has done a cam swap and gotten better mileage on the highway, but it was also coupled with a head swap, compression increase, and full exhaust all done at the same time. I went from about 16.8-17 to ~19
5.3 with a 216/220 .525/.532 114 LSA. 243 heads, Longtubes into Xpipe true dual exhaust.

Cam swaps and mileage done tent to jive too well... at least not with what you are looking for.
If you wanted mileage I would not have enough overlap to hear it and I would jack up DCR.
I have been in your exact shoes and the cam I have if pretty damn close to what I would want doing it over. It has enough chop to know its not stock, but its not obnoxious by any stretch of the imagination. I do like a little bit of an exhaust bias with the 317 heads and about -4ish overlap in something that will get driven frequently. You do have great headers though which helps.
221/226 113+3
that cam will show you a strong 6200 shift point in your truck. It wont kill mileage... but it also definitely wont help it. On the highway it will be the same for sure.

Just got a deal and picked up some 243 heads off an 02 Vette. Now I have to re-think the cam since my compression will be a 11.1.1

Talked to Geoff @ EPS earlier today, told him my stuff and use, looks like a EPS Cam Swap Package with LS 222/226 .597/.598 113 LSA
He recommended since I tow some and DD, not to be too aggressive on split.
You guys agree?
I think with the LS6 heads it will flow nice.
Thanks for the advice and steering me in right direction.
