1977 c10 6.2 L92/6l80e swap.. pics

[l92powered77]

Hey guys,thought i should contribute since i have been a lurker for a while and finally wanted to start my build thread as i also have started doing the swap into my c10. It originally had a 350 combo with the leakiest rear main seal ever to have leaked.anyways it was a gas hog and not enough power,so a few months ago i found a 2008 L92 6.2 liter engine out of a tboned escalade,1800 no accessories tho but i was pretty excited as this is my first build and im from south texas so trucks are are a big thing to us.I have always wanted a 6.0 but along came this 6.2 all aluminum engine and i couldnt say no she was for me.that was October i believe and all this time i have been reading and researching and looking at hart rods threads and dennisethe menice RIP and especially v502 thread and countless other people im sorry i cannot mention everybody but you have all motivated me to do this ls swap of my dreams.well since october i have gathered parts up the yin yang and been broke as a joke so many truck parts.But a few weeks ago i acquired a factory rebuilt 6l80e tranny for a very good price in tracy,ca and then it hit me i was ready to sell crap 350 combo and go 6.2 and 6 speed auto! So now i have combo sold and new lion heart is installed along with tranny. Just now trying to get factory tranny support bar in place and looks like all is a go. Yes I have pics guys,for what is a thread without pics!??

Alright here what im using,
Dirty dingo engine mounts for c10s of our year
Psi harness
Griffin radiator, came with efans and tranny cooler
2 magnaflow 5 inch round 14 inch case 2.5 mufflers(hate Flowmaster)
Truck intake
High mount Accessory brackets from dirty dingo

Heres where i am not sure....
HEADERS, my truck is dropped and i dont like problems someone very knowledgeable told me just order mid length seap headers on ebay,which i probaly will but as far as long tube headers what are you guys doing without frame modifications..i do not like frame cutting or c notches. I haven't thought about my rearend what should i do? This truck not race track truck this is street machine mostly cruising truck.how do i reinforce stock rearend or is it better to just buy new aftermarket?whats cheaper? I hate worrying about weak things when i could have gotten bulletproof first time around....
Any questions please away and any input is greatly needed

Hey bbbc10 thanks alot for that thread. As far as drive shafts should i buy aluminum or steel one?You would go with a locker over a posi? And gearwise what should i look into? I want a street machine with good milage I need something good for freeway and in town.I am leaving the VVT.

[bbbc10]

my buddy is running a steel driveshaft I do believe, locker/posi is same thing to me idk if my buddy has eaton or a Detroit one an he has 3.73 also an his truck runs like a mf its a cammed 6.0 with some juice...here is the link to his build thread

hey thanks bbbc10 .. thats a nice truck cammed 6.0 so sick..

.i have engine mounted now along with tranny inside engine bay by way of dirty dingo engine mounts which are spot on and I am haveing trouble with the 6L80e and finding a transmission mount for it.You see its very weird.I went to all auto parts stores and the 2 mounts they sell for this tranny wont fit onto my tranny tail end..So what am i to do does anybody have experience with this?? below are the pictures. first 2 are of the piece that came on the bottom of my 6l80e well i cant get that to mount to the tranny mounts that they sell for my tranny.I am using a stock transmission crossmember and yes i have thought that this may be my problem but i am not having issues getting tranny mount to mount onto crossmember but i cannt get the tail end of tranny to correctly mount onto the mount itself.last 2 pictures are of the tranny mounts the bigger one being the rear wheel drive version and the smaller mount being the all wheel drive version. please help...6L80E guys..

First two pics are of tranny tail end piece. Last two are mounts..

Where did you buy your engine/tranny? I saw you were in Tracy, if I can get a deal on an engine/tranny (thinking 4L80E) out there it would be worth the drive.

Actually i source drivetrain from craigslist.The engine i got in los angeles and tranny in tracy.6l80e is hard to come by at a fair price.


UPDATE.. I spoke to previous owner .Apparently the piece i have is one custom made by him and i now need the original piece that went under the tranny that fits onto the tranny mount? Does anybody know where to get this piece????

Just put a L83 with 6L80 trans in my 72 C10. Trying to solve which way to go on hooking up linkage to column. Don't want the "slop" that a lot of guys talk about in the selector lever which I think has nothing to do with linkage but the column.
WFhich way are you going?

hey welcome to the build , yeah i could have solved alot time money and hassling by going 4l80e but 6l80e swap into a old school is not too common and nobody i know has one.so yeah i wanted something different with 6l80e and im just taking it a day at a time i know i was bound to encounter speed bumps. but once done i know i will be stoked and saying it was worth it.

[l92powered77]

Update ---->more funny business as expected

Ok hey guys happy new year and i have some reporting to do.
First off i encountered a unexpected surprize by the 6l80e tranny i was sold well it turned out the previous owner from tracy,ca had it rebuilt with a tail end from a cadillac sts-v which had a oem rwd 6l80e tranny.well i was not told this when i bought it so i am having a bastard of a time trying to mount this tailend to my crossmember so the other afternoon i posted this issue and i called trans dapt and they said i should use part number 6559 at summit was priced 75.97 so i ordered that cross member with a 3 inch drop. Later that evening a forum member by name os scottybaccus? The one who owns Tejas steel works well he offered his help so now i am trying to wait and see if i can take care of my tranny crossmember problems. big pain in my neck this guy gave me a surprize from hell with this maguyver tranny. It will get sorted im sure scottybaccus crossmember will aliviate me of this. On other note i am now looking for new headers because the Gibson #gp139s headers didnt fit my truck so now i am looking for c10 ls swap headers from ebay like the dirty dingo owner told me.anyways about to send these headers back to summit they came out too much and hit frame very nice thick construction was impressed with the Gibson.made me ahha..well also looking for a engine wiring harness,the electrical one my original one is fried from all the jiggy rigging they did to it.also need something to hold my radiator in place, i have a griffin and i have no shroud or radiator brackets,any body have an idea of what i am talking about?..well im off to send my tcm to psiconversion so they can flash it with my ecm. 4th generation speed bumps as always hahaha got my harness in the mail. Gonna get new sending unit for new gas tank and get fuel system and new tank mounted.
Man o man can't wait to fire this 6.2 up!!!

Subbed. I want to do one for my '78! But I have to worry about the smog stuff.

[terrylgreenjr]

You may not be looking for shorty headers, but I used shorty headers from a 6.2L Camaro and I only had to trim about a 1/2 on the topside of the frame on the passenger side

[l92powered77]

UPDATE: Hey guys been a while. Well most parts are installed already all i need to buy is the starter and get new spark plug wires and get fuel tank mounts and hardware related. For headers i ended up ordering c10 ls swap headers from ebay and they shipped from china and shipped for 217 but they wete spot on they were a mid length design and most importantly they slid right into position and no grinding or cutting of frame was necessary! I had a heck of a time trying to solve my tranny crossmember issue and scottybaccus owner of tejas steelworks a member on this site came through with a serious solid.I managed to take a bunch of measurements of my tranny and truck and scottybaccus is the man he made me a spot on adapter plater that allows me to utilize his crossmember for my transmission.!!! So excited cant wait to turn on my truck. Will update with pics. BIG THANKS TO SCOTTYBACCUS.

Thanks man i really am hoping it is a serious reality of it becoming a beast.

One day in the future i foresee a turbo kit or magnuson sitting on top of my engine......
