[@kenitescribes8963]

Ordered the fittings for the gauges from ict the other day and ordered an rpm manifold and gaskets this morning from jegs. Picking away at it. Another question: The lift on your dodge ? I like the flex I saw on one of your videos. Whos the maker of your lift kit ? Thanks for your help.

[@kenitescribes8963]

One more question. I can just hook up the original wiring harness from the k10 right to the starter etc just like factory ?

[@NightWrencher]

The starter Should wire up the same minus the coil wire that you might have to use for ign box during cranking

[@NightWrencher]

I did the lift myself, rearched my own springs and everything. I have a video on it too

[@kenitescribes8963]

Excellent. Thanks.

I bought a daytona smart spark for my swap because of your videos. Thanks for the great content

[@NightWrencher]

Very nice, thank you for watching! I really appreciate it!

[@CountyGarage207]

We put a 6014 on my buddies ls swapped Nova, at first it seemed to work great, now it seems to run like garbage. After watching a few of your videos we decided that were going to plug the laptop into it, and see if the map sensor is even working. I'm going to wind up running an ssls on my swapped Nova. Thank you for the good info!

[@NightWrencher]

Those 6014s run great when they work. But for how long, is the question.

[@EpicToadRage]

Carb sizing is based on math. (Cubic inches × max rpm) ÷ 3456 (if you're running a V8. 3456, though looking ike a funny number, is the conversion for cubic inches to cubic feet, and for 8 cylinders) 5.3L is 334 cubic inches Google says you can take a 5.3 to 6000rpm. So, (324 × 6000) ÷ 3456 = 562.5 So, at 6000rpm, the MOST cubic feet of air a NA 5.3L can move is 562.5. But, no motor runs at 100% volumetric efficiency, so we assume 80%. 562.5 × 80% = 450. So, carb selection for a 5.3L is 450cfm to 570cfm. Any smaller will choke the engine, and any larger will give a weak signal to the venturis, causing the engine to stumble when going from idle to WOT.

[@garciareviews1455]

Sweet video! I just got a 6.0 I plan on carbing it! Throw it in my 82 d150

[@NightWrencher]

The older dodge trucks are really underated. The step sides are hard to find but you can make your own using generic bedsides and wheel tubs

[@DWBmotorsports]

By far the best thing to do on a street driven vehicle is buy a high or mid rise dual plane. Then when you go to the track install your 1 or 2 inch open spacer. This will help that dual plane act more like a single plane for the track. And it takes 10 minutes. On the LS motors the single planes absolutely kill low and mid range torque.

[@NightWrencher]

I need to do some back to back testing on the dyno with the spacers

[@DWBmotorsports]

@@NightWrencher engine masters and Richard holdener have both done it. That’s why I went with a dual plane for my NA combo over the single plane

Last question lol..appreciate all the help. I'm not doing a performance or cam jist carburetor 5.3 ..with a 350 transmission should I use a regular torque converter or 2600 to 2800 one.

[@ronchorice2021]

Question bro I have 5.3 gen4 from a yukon cathedral port.. putting in a 85 elcamino I have dual plane holly intake Daytona smart spark and edlebrock 1406 carb ... I bought a ls9 cam will my 600cfm carb be cool with that cam its goin be regular driver not racer build. And will I have enough room for a carb spacer bro.. thanks 4 ya time bro

[@NightWrencher]

Hey man, the 600 should run fine. You might need to do some tuning it get it to run clean but the same goes for any carb. Edelbrock carbs are more forgiving so it might work out without issues.

[@johnnyhurtado3035]

[@BigHatsince98]

I totaled my 02 2500HD, it still runs rides and drives but the frame is bent and it only has a limited amount of time before reaching terminal failure! I also have a solid 3rd gen Camaro just sitting in my back yard. Thinking about transplanting but this looks like a lot of work. Any tips? Don't bother? WDYT?

[@NightWrencher]

The engine should drop right in using the camaro transmission if it's a V8. You would need an adapter flexplate and spacer for the torque converter and adapter plates for the motor mounts but aside from that, the rest should be easy. Run the factory EFI harness, order a flashed PCM for like $150, install a high pressure fuel pump, install fuel injection rated lines, corvette return style regulator and you're basically done. Going carbureted might be easier but it is more expensive

[@NightWrencher]

If the camaro does not have a transmission, I don't know if the transmission tunnel in the 3rd gen is big enough to acomodate the 2500HD transmission

[@BigHatsince98]

@@NightWrencher It's got an LT1 in front of a 700R4. The 700R4 was rebuilt but I need to pull the valve body and check for sticking valves because I only downshifts manually. It has sat a long time so that might be part of it.

[@NightWrencher]

The 700r4 should hold up fine if you're not too reckless

[@markgarcia5417]

Do we have to do anything special for the coolant tube up .small radiator hose I think it's like 1/4

[@NightWrencher]

You just run that back into the top radiator hose. Its to remove air bubbles.

[@markgarcia5417]

You think a off brand intake .with elderbrock be ok..what's your opinion on off brand intakes for the ls

[@NightWrencher]

The chinese intakes are just copies of the holley intakes. Not as good as a real edelbrock intake but good enough to drive around. An edelbrock carb is fine as long as it runs decent out of the box. If you gotta tune it, I cant help you on that one

[@duanehenicke6602]

The good old carburetor. I remember those. I would think they would be a nightmare with todays fuel. They were a pain with the old fuel. Lots of carb rebuild kits sold back in the day. How do you keep the engine from overheating with no fan shroud?

[@NightWrencher]

It actually runs pretty flawless, the key is in a modest tune. Not too rich not too lean. The engine is iron block but with aluminum heads, slightly rich tune and the radiator is larger than the stock one for that engine so I havnt had any issues even on a hot day like today in uphill traffic. I'm planning to make a nice shroud, just need to make sure it clears everything. I had the engine over heat once but that was because the fan clutch that came with the junkyard engine stopped working and wouldnt kick on anymore

[@duanehenicke6602]

@@NightWrencher That's another thing the carburetor trucks didn't have. Nothing but flex fans. I've actually toyed with the idea of putting a flex fan on my 91 w250 diesel.

[@NightWrencher]

I never really liked flex fans. The stock dodge truck big block radiator is massive so the clutch fan rarely kicks on, especially on the freeway. The radiators on the newer 1st gen trucks are smaller. Idk about the diesel trucks but I'm willing to bet the older trucks had bigger radiators

[@duanehenicke6602]

@@NightWrencher Mine's early 91. Came with a small 2 core. Ran hot everywhere it went. Installed a aftermarket aluminum big 3 core. Built for the truck. Cost big $ but it was worth it to get it to run cool. Also installed aftermarket intercooler at the same time. Very tight fit but it works. Dodge didn't put the bigger radiators and intercoolers until 91.5. Been wanting to upgrade the turbo for yrs. Just haven't found a setup that's turnkey. I don't enjoy turning wrenches like i did when i was younger. Rather not do a lot of modifications for the upgrade.

[@NightWrencher]

I have 2 parts trucks, an 85 and an 88 and I was planning on reusing the core support complete for my ramcharger but the radiator was so thin, I'm juat going to modify the support to accept an older style radiator. Theyre still pretty expensive, almost the same cost as a fancy one. But it keeps my stuff cool so at least theres that

[@engmentor6229]

Hey man love the videos. I’ve got an LM7 and 4L60e. I’ve heard of people running the stock ECU (Cam/Crank/MAP), and wasn’t sure if you considered or heard about that. Don’t see any reason it wouldn’t work with a carb. Thanks for any help!

[@NightWrencher]

Hey man, you would have to go through HP tuners and creat a custom speed density tune that would ignore the fuel injectors and run spark only. You would also have to run a compatible TPS on the carburetor in order to run the electronic trans. Its not hard but its not that easy either. If you dont use the stock computer, youll have to run a trans controller for the 4L60 instead. Hope this helps

[@nicklemley7763]

I need help trying to figure out what I have to buy for my motor

[@Platos_Rave]

You saved me from msd, thanks. Hadn't come across Daytona spark, looking forward to reliable hassle free ignition control. I've got a question regarding fuel lines. I have a v6 4th gen fbody. It came with a return still system. Do you think it's feasible to plumb install a regulator similar to your setup using the existing fuel lines? In your video I see two lines to your regulator, are using a return system?

[@NightWrencher]

I am using a return style system on my truck. Since your car was EFI, the stock pump is probably like 40psi so you'll want to install a regulator and a return line back to the tank. Hope this helps!

[@Platos_Rave]

@@NightWrencher regulator for sure. Would stock efi lines work or do I need to size up or down. Thanks again, these videos are a great resource!

[@NightWrencher]

If your stock lines can be moved and installed on the regulator without damaging anything, you can reuse them no problem. They should be big enough for your swap

[@domecrack]

Holy smokes. It's all here. In a 13min video.

[@domecrack]

Any other KZbin channel would have made this video in 3 1hr parts, cuz it's good for their metrics. I was literally just wondering about this. I'm angling for an 04 GMC w/ a 6.0, and since it's the east coast, it's about to molt, so I'm thinking about nabbing a 70's wagoner or something from out west to drop the important stuff into, and I wasn't sure if I could run a carb or not.

[@NightWrencher]

It has a learning curve, but if you have patience it can run even better than EFI

[@domecrack]

With 8000x less headache I bet.

[@NightWrencher]

Well, it depends, the box has 9 preset tables bit you can only run 1 custom one because it does indeed have to be uploaded. If you upload the custom map and then turn the dial, I'm not sure what happens but I'm assuming it will just switch to the new preset and your custom one will still be logged there but I'm not sure

[@NightWrencher]

I have a playlist called ls swapped dodge. There might be some info there and part 2 of my build also has info. Same playlist

[@BCGgaming1]

Serious question why does one need to change stuff to do with the trans for a carb conversion?

[@NightWrencher]

Because the transmission is computer controlled on efi ls engines. When you go carb, the aftermarket ignition modules dont have built in trans controllers so you either have to go with a non computer controlled trans like the 700r4, th350, th400, etc or find a trans controller that works with the trans you want to use or convert the newer trans to use a manual valve body.

[@BCGgaming1]

@@NightWrencher I'm curious if you could possibly help me with all of this. I'm wanting to convert to carb to get rid of most of the wiring as possible especially the throttle wire. Do you have a list of everything needed to convert? I'm trying to decide if I should carb swap it or just do a throttle cable conversion. The throttle cable conversion involves having to have the engine tuned which I'd rather not have to deal with. I know this is asking a lot but I'd be forever grateful.

[@NightWrencher]

In the description of the video there is a parts list of what you will need with options. Total it up and see if its worth it for you to pay that and also buy a wideband and learn carb tuning because no carb is perfect out of the box. I have over 30 videos on just carb tuning alone that you will have to learn if you want everything to work right. If you have something that came factory with an efi LS like a silverado or camaro, leave it alone, you will only make it run worse with a carb I guarantee it.

[@gregrandall5635]

What is the difference in the ls1/6 and ls2/7 wiring when ordering the ssls?

Hi Nightwrencher! I have a bit of a complex question regarding bypass fuel regulator. I have a 1993 foxbody that was originally a 4 cylinder, putting in a carb'd LM7. I've got the stock mustang in tank fuel pump and stock fuel lines. From my research the stock mustang fuel pump puts out somewhere between 55-90 LPH. Can I use the aeromotive 13301 bypass regulator? Or do I have to get the overpriced Aeromotive EFI to Carb dual stage regulator 13220

[@NightWrencher]

It honestly depends on the size of the return line and how much fuel the fuel pump puts out. Ive ran pressure regulators that would work fine on some fuel pumps pump get conpletely over powered on other fuel pumps. According to the parts book, the 1993 4cyl mustang has an 18gph pump at 51psi so the 13301 should work fine on that application

I've got the passenger side with a filter on the nipple and the driver side off the PCV valve with a 3/8 hose thats hooked up to the carb base plate. If you have a brake booster and only one 3/8 fitting, either add another fitting or T off the line going to the booster as close to the baseplate as you can to prevent oil being fed to the brake booster.

[@ibrahim-chevelleMalibuman]

I have a question please . Is the edelbrock Avs2 800 cfm enough for stock 6.0 LS . and the msd box is works right out of the box just ready to go or you need to re program it .That’s it thanks a lot .

[@NightWrencher]

The msd box is designed to plug in and fire up. As long as you plug in the vacuum hose to it and the onboard map sensor hasnt died then it should get you going. A stock 6.0 with full acessories is 300whp with a redline of 5k with stock worn out valvesprings. Even a 650 is more than enough for that low of hp.

[@ibrahim-chevelleMalibuman]

@@NightWrencher thanks for the replying . Does the carb make more hp than EFI . Because in your video screen you typed +50 hp . Thanks again

[@NightWrencher]

We'll it depends. The gains come from modified engines, stock for stock, the EFI will make the same or a bit more hp but a dual plane carb intake will make more low end torque

[@ibrahim-chevelleMalibuman]

@@NightWrencher is there narrow or low intake manifold for this application because I have an 81 Malibu I don’t think it’s gonna fit under the hood. Thanks for your help . You are awesome .

[@NightWrencher]

The dual plane and mid rise intake single plane have only only a .060" inch difference in height. The hi rise or super victor are way taller so a dual plane with your edelbrock carb is as low as it can go. They make low profile air cleaners so maybe itll fit. If not, you'll have to go EFI because they have lower manifolds like the LS6 intake. If someone has already done this swap before on that chasis, you should be fine
