If you have any questions, ideas or suggestions for this truck, drop them down in the comments! I will respond to every comment!

[@bcdieselsofficial]

I have an LB7, and it is one of the best trucks ever built! I would suggest installing a 6 speed transmission conversion kit.

[@ConnorRydland]

@@bcdieselsofficial the 6spd valve body conversion is ok if you aren’t going for power. If you are going for power it’s best to stay with the 5spd because the clutches will get fried.

[@bcdieselsofficial]

@@ConnorRydland do you know exactly how many differences there are between the 5spd and 6spd besides the valve body, TCM, and some return springs? Because I wanted to build power and still be able to get good fuel economy. Anyway, I am smashing that subscribe button!

[@ConnorRydland]

@@bcdieselsofficial I still get 22-23mpg highway on mine, but your best bet would be to literally swap a 6spd allison 1000 in your truck

[@bcdieselsofficial]

@@ConnorRydland that’s probably the best move. I have some vids on my channel.

[@shemwhitehead9517]

Good to see a built out diesel truck that's properly tuned so it doesn't smoke.

[@ConnorRydland]

People don’t understand that if you maximize the combustibility of the fuel that it shouldn’t smoke at all. I’ve been running Hotshot secret EDT and the quality of fuel is just perfect

What new crank did you do and are those cast or forged fingers pistons

awesome truck brother. my brother just got a cat eye lb7 and we are just now getting into the diesel scene. keep the updates coming, i'd love to see where you end up going with this thing

[@garrettmalo]

what is the wheel and tire looks good on stock height

[@willnichols8223]

What size wheel/tire/lift is on the truck

[@dylans4788]

Kick ass truck! I think you should “reverse level” the truck with some drop shackles and have a little more stance with the wheels and tires. Most badass look for such a fast truck. Btw, high idle started on the LLY’s in 2005 😁

[@ConnorRydland]

Yeah I’m definitely leaning more towards dropping the rear, and good to know that it started on the LLY!

Do a fleece tap shifter, kryptonite front end, and I’d say reverse level it with all that power, also window tint would be nice

[@blondeguy08]

How do you like your transmission? Is it holding up to the power?

[@ConnorRydland]

That’s a long story…. Need to make an update about that. Broke pretty badly and I went to a full billet build from Precision Power in New Holland. Now it’s great!

[@MrPing93]

What wheel and tire size is on that truck? Also, what size lift on it?

[@ConnorRydland]

I need to double check the next time I see the truck, it’s been getting a new transmission. It’s either a 20x12 or a 18x12 on a 33 or a 35. It rubs a lot lol but the offset isn’t out very much

[@mitchparson1878]

Is your truck stock height? Also, what are the wheel and tire specs? They sit perfectly outside of the fender. I’m wanting the same look for mine. Awesome build dude! That thing rips!

[@ConnorRydland]

Stock height yes, I’m waiting to get the truck back from getting the billet trans to remember the specific wheel specs

Looking at a lb7 would you recommend, and have you had any injector problems

[@ConnorRydland]

It’s a good motor as long as the injectors have been serviced! I’d recommend! I’ve never had injector issues, but I have SAC style 150% overs that solve the spray pattern issue

[@erikoltmanns4568]

Ok thanks just heard a lot of bad things

[@ConnorRydland]

@@erikoltmanns4568 yeah overall the lb7 block is a pretty good block to work with, until you push power. Doesn’t have crank issues like LMM’s, head gasket issues like LLY’s, piston cracking issues like LML’s, and there’s no emissions so it’s a safe platform to build. The big issue is just the valve covers and the labor it takes to get them off to do injector work

[@timmothyshad1137]

what gauge cluster does it have?

[@ConnorRydland]

It's an escalade cluster

[@silverrain99205]

[@zmax765]

6 speed conversion or still 5 speed?

[@ConnorRydland]

5 speed. 6 speed conversion isn’t worth it, especially with high power builds. The 5 speeds have the clutch packs for it, you just have to change valve bodies. But the clutches will wear out fast if you’re towing or pushing power.

[@brockwolf2962]

My 05 lly has high idle if anyone is wondering about theirs

[@That2strokeRider]

Was this build worth it? I am thinking about doing a similar build on my lb7 but I know how expensive diesels can get, would I be better off just buying a car and making 1000hp or a truck? Is the truck fun? Just don’t want to dump 40k into my truck and have something less fun than say a whipple cobra with 1000hp.

[@ConnorRydland]

I mean that’s a yes and no question. Depends on what you want, if you want a truck with enough power to spin the earth, go for it. Trucks can be driven year round, and have more space.

[@That2strokeRider]

@@ConnorRydland thanks for the fast reply. I am still debating, I need to find someone in my area with a built diesel and give me a ride, At the end of the day 1300hp is retarded straight up. I smile and think my lb7 with a ppe tuner is fast lmao. It needs a rebuild so I might just build the motor and send it. Have you ran your truck in the 1/4 mile yet?

[@ConnorRydland]

@@That2strokeRider it’s honesty the torque and the fact that you’ll get wheel spin at 90mph that makes these things wild. I haven’t ran it down the track yet, I am actually still getting my rebuilt transmission. Shop 1 screwed me over so I had it pulled and towed elsewhere to finish it. It’s been 7 months now… but idk how it would do at the track. A much more simple setup would probably do better, this is more of a dyno/sled truck more than anything. The torque wears out clutch packs pretty easily

[@That2strokeRider]

@@ConnorRydland oh really? Do you know what would hold that power? I figured the stage 6 ppe kit would be what I would use and just build it myself with the help from my old man, hes a master heavy duty Diesel technician. Thanks for taking the time to reply though I really appreciate it. And really sweet truck!👍

No 6spd valve body conversion, it wears out the clutch packs too quickly in high hp scenarios

Do you have lift pump

[@ConnorRydland]

Yes fass 150 underneath, it’s hidden under the center frame rails

[@hunteralmueti5815]

Just out of curiosity sir, what if you mpg on that kind of setup?

[@ConnorRydland]

I would say averaging about 16mpg, haven’t exactly tested it yet!

[@moparkr]

not that im doubting the numbers but, i put a fass 150 lift pump in my 01 lb7 dually that is completely stock, except it has a banks 6 gun tuner (came with the truck). anyway the fass 150, even the 165 (just looked it up) is only rated to 600hp (150) and 600-900hp (165). i am really doubting that the 150 can keep up with twin turbo's, 150 over injectors and still making 1300 hp as you listed. i'm not saying it cant but it may be something to look at, it likely isint making the hp numbers claimed.

[@ConnorRydland]

Those were my thoughts exactly too, sounds like I need to make a video breaking that down! Fuel rail pressure stays extremely high with the dual Fuelers, so that’s a great question!

[@cwbywy9544]

@@ConnorRydland The dual CP3s/CP4s or whatever you said was in it are designed to pull fuel. Stock trucks don't have a pump fuel pumps. So, you got twice as much suction and a fuel pump. It's feasible to have enough fuel, even if the pump is freewheeling. lol.

[@ConnorRydland]

@@cwbywy9544 yeah it makes sense, I’ve also seen guys running dual lift pumps obviously pushing ridiculous amounts of fuel, but this setup is very solid for the 150% overs with consistent strong rail pressure at 26k-28k (I forget, haven’t driven in a bit, trans is getting rebuilt)

[@donaldthomas5852]

@@ConnorRydland I have a 2001 Chevy 2500HD LB7. I am looking for a set of bigger towing mirrors something like what you have on your truck . At present it has the smaller stock mirrors . And I just bought a RV camper and it at least 8 ft wide and it hard to see around its. If your interested in selling your mirrors I may be interested if they are like in new condition. My 2001 Chevy is in fantastic shape with only 95,000 miles and been garage kept only time it saw daylight was when it was being drove. So headlights are not faded paint still in near new condition . Never been driven by anyone under the age of 54 years of age. I bought it from the previous owner who bought it new they were 75 Yrs old . It does have a K and N cold air breather and tow tuner. The truck is as t tight as a new truck. So I am thinking it has somewhere about 300+ hp and 600+ toque which is all I need . Not interested in making it a drag truck. Interested in how long I can make it last without spending money on it, ha ha , really I am 66 years. I do love watching Duramax truck pulls and like it when they beat the Power Stoke and Cummins. Even though I love the Cummins engine. I drove trucks most of my life . Drove many different Diesel engines. Detroits , Cats , Duramax ,Maxidyne they were in Mack trucks and Cummins which I believe to be one of the best. Back in 2005 & 06 I drove for a auto auction company delivering automobiles in a 4500 or a 5500 Chevy trucks that had Duramax lb7 ‘s they ran great and pulled good , better then the Ford Power Strokes they had. We would put about 300 + miles a day 5 days a week on those Duramax’s running them at 75 mph pulling loads ass much as 25,000 or more lbs.
