I loved the performance aspects of my Truck norris in my 1 ton, but I disliked it so much when towing 11-14k. Mines 5 speed and I had to stretch 3rd to 6k rpm just to sort of bridge the gearing gap to 4th. Now, 3,500-5700 rpm....she would get it, but Went back to factory cam and custom tune and LOVE IT. Miss my chop and playing with 1/2 tons empty lol, but i tow too much. Love the truck amigo, keep the content coming.
@@JohnnyAnderson1 If I stretch it out to 6k then I usually end up around 2650-2700 coming on in 4th. Then 4th is fine unless I come up to some good grade hills, then I got to drop back down to 3rd and stretch it out and hold it. Ratio of trans in 3rd is 1.67 then 4th goes 1.1 and I'm 4.10 factory geared. 285's don't help much either. My heaviest load yet was my 40' trailer with my 84 JD450 dozer on it and it'll move it, but 50-55 is all she got and I shifted way more than I like back and forth between 3rd n 4th. Not mention stopping it even with trailer brakes. Which that's a LOT of load for a gas single cab 1-ton.
@@JohnnyAnderson1 yeah that's why it's only towed it once. My Dmax moves it no problem. It usually only moves my 5th wheel or my 24ft concession trailer with my smoker. I've almost been tempted to put my built 4l80 in it and see if I like it more, but I done pulled the cam.
love your videos, they're real world scenarios so it's interesting to see! your firebird is cool as fk too haha. That's almost 6 ton, good effort ngl, we use diesel 2500HDs here to tow less than that in Australia hahaha because our Japanese utes can't even tow 3500kg without sacrificing passengers and other stuff in the bed because of GVM/GVW. Good rigs GMT800s with the 6.0, shame we didn't get many of them here. common rail diesel sucks to maintain and $140k AUD for a 2500HD is obscenely expensive, better off buying a 11 ton GVM cab over truck.
Haha, thanks. I wouldn't wanna pull that much on a daily basis with this truck ,that's for sure lol but man that socks yall don't have many gas options.... are the emissions just as bad in Australia as they are in the US on diesels?
Glad you got something put of it, yea a before and after would have been ideal. If I knew someone with a stock 6.0 truck that would probably be the easiest way to do that.
I have pretty much the same setup as you minus heads.. still have the 317s.. I had a shop do the tuning on mine and my throttle likes to hang. Did you run into that at all? And yours seem to pull waaaay harder than mine. Do you think the heads made that big of a difference?
Heads shouldn't have made a huge difference. What gears do you have? Weird, I also had the "throttle hanging" situation, but it was tune related. I believe in the DFCO settings and rolling idle table, may have been something else too.
@@JohnnyAnderson1Mannn, I’ll be honest with ya I bet that trailer only weighs more than 3k I bet it’s more like 5k, I’m guessing you was roughly pulling 15,000ish
@jacobdewitt1243 Yea it's fairly stout for what it is, I wouldn't tow that much all the time with jt but say it was once a month or so it would be totally fine. It's definitely stronger than it was!
Thank you for these videos. By the way, what kind of trailer is that? And can you put sides on that trailer so you can carry stuff in it other than cars or trucks?
Runs decent. I'm about to put the same cam in my LQ4. That load is just too heavy for a 4L60e. A stock cummins or duramax would decimate any gas motor with the same load.
@@JohnnyAnderson1 exactly. You can also much more easily work on your own ls motor than a diesel, especially a duramax. I remember being shocked when I realized a rebuild is 20k.
Truck would have done a lot better if you threw it in tow haul mode, let the convertor unlock, and let it downshift to 2nd the few times it needed it. I totally get just taking it easy with a trailer though. I've towed about 6 - 8k lbs campers and trailers with wood beams behind a HO 24v 5.9 cummins in an 06 Dodge and it's good when cruising about 70mph but it struggles up hills all the same. Pulled 5k lbs with my LQ4 2500 and didn't bother pushing it either, felt very much like the diesel with a camper around the same weight. Gassers do an awesome job they just love to drink.
Yep they are very thirsty for sure. I have the trans setup to lock with the tow hual mode with a highly modified transmission tune. Under heavy acceleration your right, I do leave it unlocked untill the desired speed is reached. So yea if I wanted to just lay into it 100% I would let it down shift and Rev to the moon lol.
@@noeltrejo9756 depends on weight. with lighter towing, if you feel like your truck could lock the convertor don't bother with tow haul. Might help to engage tow haul when speeding up to hold gears longer then disengage so the convertor locks earlier. with medium size loads probably best to use tow haul and with heavy loads or hauling through Hills best to go to D3 for less gear hunting. 3rd is best for heat, and also in D3 the overrun clutch engages (in 1st,2nd,and 3rd but only in the D3 position) which helps the transmission hold better
2500hd with 1500 front clip, I'm running headers for a 1500 but had to slightly bend a header tube in to clear the front driveshaft yoke on the differential, like 1/8 of an inch or less. The y pipe for a 1500 will not fit with the 80e without modification also.
Im planning on running 243 heads and the truck Norris cam in my lq4 Is upgrading to longtime headers worth it? I already deleted my cats was just wondering if it’s needed or can I run stock manifolds
You can run stock manifolds but from every dyno I have seen the headers are good for around 15-20 ftlbs of torque below 3000rpm. And they sound good lol
@@JohnnyAnderson1 how are the driving habits unloaded for you with the 4.10 ? was looking to go to 4.56’s on 295/7516’s after the cam set up currently have 3.73’s
@Marcusmendoza002 The 4.10s are perfect for me with this size tire. But if I had 3.73s I wouldn't waste my time by going to 4.10s, I would just jump to 4.56s.
@corycomp545 I tried 87 and it wasn't worth it for the low timing I had to run while towing. If I dailyed jt I would keep the timing low and just run 93 for towing.
Appreciate the response thinking about going with this cam in my truck now my last truck was a stage 4 truck cam with 3000 stall and the onley thing that you could run was 93 or better it wuldent even began to run on 89 even without spark nock got a 02 2500 like yours and just want little more kick without being stuck to 93 or race fule like the last truck lol drive it daily and tow weekly if not multiple times a week . Thank you for your info and keep up the good work on the videos injoy someone that's doing that same as me with a Gass truck and not jumping straight to a diesel
@corycomp545 Awesome, and glad the content has been useful. If I was still running the stock 317 heads I am certain I would have zero issues with running 87. It would cost a tiny bit of power (maybe 15 hp/tq) but if it was my daily I wouldn't care. Even with this compression ratio if i keep the timing around 23 degrees in the high load areas it doesn't knock on 87 (around 2500-3500 rpm is were it would knock under load). But with 93 I can run the timing on up around 30 degrees which is certainly not a night and day difference, but it does seem to pull harder. Is it worth an extra $15 per tank of gas is the question though.
@@JohnnyAnderson1 That's kind of a shock to me, so you're telling me that under the same conditions with nothing else changing except for the stock camshaft to the truck Norris camshaft, you experienced a zero mile per gallon loss? Sorry I just wanted to double-check. Thanks!
@m.armstrong53 it really comes down to the efficiency of the engine in comparison to the work its having to perform whenever your dealing fuel mileage. What I did improved the engines ability to make power, so it has to work less under the same conditions. Now if I wanted to drive it hard it would be able to burn more fuel than a stock engine, if I accelerated as slowly as the stock engine did I would even bet it would get better economy than it did stock. Probably not a noticeable difference though. I did headers, and added 799 heads to bump compression 1 point also.
