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. 224/228 114 LSA

2. 220R-112 LSA

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. 220/224 on a 112 LSA

10. 221/226 113+3

11. Your cam and advice?

Thanks for the help. I have no experience with cams, just FYI.

And

Add in some PAC 1218 springs and 7.4 Comp magnum Pushrods at cam install?

And new set of GM LS7 Roller Lifters Part# 12499225 too($98)?

or Just do the
COMP Cams GM LS1 LS3 LS7 Retro-Fit Rocker Arm Trunion Upgrade Kit #13702-KIT ($129)

I'd go with something like a SDPC HT1(214/218 111lsa+2, lift.559"/.562") . This cam has fairly mild cam lobes would have -6* overlap and a IVC of 36. I'd use a set of PAC 1218 valve springs, do the trunion upgrade on the stock rockers, an get LS7 lifters and new lifter trays, an measure for proper PR length needed.

BTW, I'd also get around a 180* t-stat, a 160 t-stat is too low!

Seems you are headed in the right direction man and doing mods in order and accordingly.
Ill agree with said above cam that 99bluz mentioned and as said you need to look at overlap to help determine the "chop" or "lope" at idle.

Side note: id choose the yank truck truster over the budget circle D. Locally iv seen alot better 60' times come from the yank TT over the budget circle D converters

Yank Truck Thruster Series 2600 or 3000 stall? I still tow just a bit, is the difference that great?

VortecMaxx06

222/226 113+2 .604"/.604" cam for your application, Geoff advice. Looks good.

Four things:

1) How is a WIDER tire going to affect rpm when the overall diameter (70/17) isn't going to change?

2) If you're doing the lifters, grab a set of LS2 lifter trays. Even if you already have them, I'd put new ones.

3) Any thoughts on running a .040 or .045 head gasket for an additional bump in compression?

4) I'd pass on the Comp trunion Kit and get the ones Brian Tooley sells. They're made of a more durable material... Better quality.

I do agree with the "Get Goeff at EPS to spec you a cam" statement. You will not be disappointed, and you won't beat the **** out the valve train using his proprietary EPS lobes.

1. 265/70R17 = 31.6x10.4R17
285/70R17 = 32.7x11.2R17
= 1.1" Taller

2. Good idea, thanks.

3. How much more would it raise it will the .040/.045?

4. I'll take a look at them. Thanks

5. His reviews are pretty good across the web, and he was a pleasure to talk to on the phone, not telling me what I have to do or pushing a sale. Just advice and his past experiences.

The 1.1" taller tires will only change you effective gear ratio from 4.10 to 3.96, so your gearing will still be really good.
With .045" head gaskets your SCR will go up right about .14, and with .040" head gaskets it'll go up about .26 .
As far as EPS cams I would look at the TT2 (218/226 113lsa) if you want a bigger cam, but I wouldn't go any bigger with towing and with a 3k stall TC..

265 is the width in mm
70 series means the sidewall is 70% of the width
17 is the wheel diameter.

70% of 285 > 70% of 265

Right right right. Forget number one. Brain fart. Lots going on today...

"Yank Truck Thruster Series 2600 or 3000 stall? I still tow just a bit, is the difference that great?"

The 2600 will retain stock towing capacity, the 3000 will be slightly less ideal.
They are both built on a 278mm platform so i wouldn't hesitate to tow with either.

Depending on the cam you choose to use, would determine the stall speed.

I still think the SDPC HT1(214/218 111lsa+2, lift.559"/.562") or even a custom grind from Cam Motion with the same specification is a better overall choice for his needs/ wants, but I have to admit this is a better option than the EPS TT2(218/226 113lsa), if he's going to go with a larger cam.

Any way I only suggested the EPS TT2 as a better option than the larger EPS 222/226 113lsa cam.

Calling in the order next week with EPS, I'll talk to him about the TT2 Cam. I like the lift being under.600 on valve springs.

Let ya all know how its goes once its in and post a video clip.

Geoff is an absolute WEALTH of knowledge. Be prepared to be on the phone a minute... He takes a LOT of time to ask you questions, what you want / goals are, then makes his suggestion. It doesn't end there though. He takes the time to explain WHY he's choosing this, that, or the other. His service is phenomenal.

I've watched him do it about 100 times and every time I learn something new. It's pretty cool to hear it.
