Re: Gen V Engine swap info
Sounds like you are farther along than i am. Did you have the vats removed from your ecm yet? If so did you send it out or have someone local take care of it. I still need this done.

Re: Gen V Engine swap info
I sent it out....there wasn’t anyone close that was experienced with the L83/86 PCM reprogram.

Re: Gen V Engine swap info
How did you bolt on the power steering pump, idler etc...Thanks

Here is Motechs power steering mount adapter. Uses a 2012 Jeep wrangler pump. Also is a view of their standalone harness with ECU/Bussman mount

Billet ac adapter to convert the ac compressor to standard fittings

Re: Gen V Engine swap info
Nice, how much. The Motech PS solution is good but I still rather have it on the driver side tho. Who modified the stock harnesses for L83 swaps?
|
Re: Gen V Engine swap info
I think its 80$ for the billet adapter. I modify harnesses and do programming if anyone needs it done.

Re: Gen V Engine swap info
What engine mounts are you guys using? I have a 74' C10 and currently have the Dirty Dingo mounts. The problem is you have to move the AC and delete the vacum pump for the mounts to fit in the engine correctly which leaves the issue of brackets to mount the AC unit in top of getting a bracket for the power steering. They do make those brakets, but spending $600 in brackets alone in top of replacing the AC unit with a different one along with a different water pump is a bit pricey. If that is the route I need to go so be it I will bite the bullet but would like to see what other options are out there.
If I read this correctly you do not need the BCM for cruise and tap shift correct? If that is the case what do you have to do? Also if you are using those mounts what are you doing for headers? Any other information is greatly appreciated. We are just getting back started and have yet to set the engine in the truck yet for our 1st test fit. Sorry guess I should mention it is a 2016 L83 with 6l80e trans. |

Almost positive it wouldn't fit a square body. https://imagizer.imageshack.com/img924/7606/BEEor3.jpg I modified the stock hose ends. Close but clearance is there. Clint |
Re: Gen V Engine swap info
The bcm is not needed. Tap shift can be controlled with a unit from motech along with the serial ac command and park/neutral safety output. I can only get cruise working so far with a rostra unit. To many inhibitors on the new gen v systems to bypass. If dirty dingo mounts do not work well i know someone here can fab up some that will work. I did on my 96 tahoe. I got the factory vacuum pump and ac along with the other accessories.

How much is the unit from Motech? Just trying to see what my options are. As for the Dirty Dingo motor mounts they will work and I will probably go with their accessories brackets when said and done. I just need to figure out if there are any shorty headers that will work in my 74' using their motor mounts. Since there is not a lot of information out there I am not sure what if anything is available to work with them. Vanatta20 another question for you as well since you seem to know your stuff. I bought the Walbro 255 fuel pump. That should be plenty big enough pump shouldn't it for the fuel system? Still trying to find more info on what exactly needs to be done there since we don't have the FCM. Do you basically set it up similar to the LS system and use the Vette system with it? Any advice would be appreciated. |
Re: Gen V Engine swap info
There might be some shorties that fit a stock truck so try your stock manifolds first. There are only a couple LT swap long tube headers (BRP is one) but they are not cheap.
|
Re: Gen V Engine swap info
On my swap, I have the fuel pump and corvette filter feeding the high pressure pump on the back of the motor.
Idk if my pump is the Walbro or not...I was told it must supply 75psi at all times. I believe that’s correct. |

My 1976 C10 is done. It has a 5.3 gen v with the LT1 intake setup. 6l80 with a 3k stall. Texas speed stage 2 cam. It runs great. I have a electric power steering pump on this build and a 2016 Camaro as fan.

Re: Gen V Engine swap info
Lovin’ it!!! I’m getting closeer to installing your harness on and giving it a go. What did you do with your transmission lines?

Re: Gen V Engine swap info
Bringing this thread back from the dead! I see Vannatta20 hasn't been on here since September, but maybe someone else has some answers. What is everyone doing to control the alternator in an LT swap? I'm thinking without the GBCM, or what ever they use now, it will default to the 13.4v that the older swaps would do?
|
Re: Gen V Engine swap info
Ive seen it on the stock c-10 gauge where it drops below 12v, but I don't know how accurate the gauge is either. The power going to the cab is 10ga tefzel wire (quality good stuff) strait from my buss bar fuse block which gets 2ga battery feed to it. No interior sound system yet :( just exhaust notes.
I have a massive 650watt radiator fan that runs at 10-15% a/c off, but when a/c is on, it runs 85%. Its random when the gauge reads lower voltage than I'd like to see but I have no problems with it. Most of the time, its above the 12v mark. Truck sadly gets a hard ride once a month maybe, and is stored with no battery disconnect or anything and starts like a champ. (800cca AGM battery). clint |
Re: Gen V Engine swap info
Lots of great info in this thread! I'm getting ready to a L86/8L90 swaps in a 93 and then an 84. Looking forward to contributing some good info in here!

Re: Gen V Engine swap info
My swap has begun and stalled for a little.
72 K5 Blazer L8T 6.6 from a 21silverado 2500 with 25k miles 6l90e 2wd from the same truck Planned to go 2wd instead of 4x4 but I am stuck because I kind of like the 4wd for utility purposes. I kind of thought about going 2wd prerunner style but I am stuck with indecision. I want to run Holley terminator X max but I am also stuck trying to figure out if I want to spend the extra $$$ on direct injection and it's potential issues or convert to Gen IV by deleting the direct injection. 4wd is definitely much to complicated and requires twice the funds for various adapters and such. I definitely feel like going 2wd for simplicity and lower cost. Currently laid off from my job so everything is at a standstill except my custom 304 Stainless tank that I will be building. I have the the materials and the time so why not!?! I will be going with like 28-30 gallons. Once I run out of argon though, that will have to hault too. I have been funding my swap by selling off my beloved excess things. Mostly cult classic car audio gear (speakers, subwoofers, etc.) I may sell my custom chopper if too much time passes without an income though. |
