What company (if there is one) makes a mount setup that will put the ls motor in the exact location of my current engine. i found 20 different companies that make them but through research they all move the engine forward. I am going to run my 700r4 and do not want to have to move it. And i dont want to have to go through the hassle of tryig to modify some to make them work. if i have to i will but would rather not.
And could someone tell me how im suposed to use THIS. does it make it where i can use my 700's flexplate and converter or does it make it where i use the ls flexplate and 700's convertor. just trying to get all of my ducks in a row.
Is the engine going in your 84 or something else? When I installed mine in my 90 I used the original location of the 700r4. And it sat in there with no modification to the plates.
Here is where I got mine.

yes its going in my 84. and the reason i want clarification is ive read where some mounts move the engine forward.Quote:

I know there is a couple more that have done on the 73-87 trucks. They may chime in.
i talked to him over on pt.net and he moved his engine and trans way forward. i think it was close to 4 inches. thank you for helping me look though. :)Quote:

I found that one in a search this a.m. he used a 4l60 and modified his crossmember though. finding someone who used a 700r4 in the exact same location as it was installed from the factory is gonna be harder than i thought.
If you bolt the 700r4 to the Gen III engine and then install it, it should work. Just use the 84's cross member as a guide. Bolt the trans to the cross member and the cross member to the truck frame. For this you will need the adapter plates installed.
i hope those plates put it in the correct spot. i reall dont want to have to mess with adjusting or moving my shift linkage and stuff.Quote:

ok. thanks for the help. if it doesnt work out i will let you know.
I used some plates from Trans Dapt Performance Products - Engine Swap Motor Mount Kits part #4572. I had to drill new holes in the frame to move the tranny cross member but other than that everything was good.
see thats what i dont want to have to do. i dont want to move my trans. then i will have to mess around and cut/modify my shifter linkage and my driveshaft will end up beeing to short.Quote:

I feel your pain. I am installing a 5.3/4L60 into a 1972 Jimmy with an NP205. I am leaving the NP205 in the factory location so I don't have to mess with 2 driveshafts and a shifter. I am running into engine mount and crossmember issues. The front differential will be very close. Everyone does these swaps on 2WD vehicles. Not very many 4WD stock height vehicles.
Good luck finding what you are looking for. I am also looking for 1/4 inch thick adapter plates. All the 5/16 and 3/8 plates are messing with my engine height and distance between mounts?!
I was lookin at my swap stuff today. I am puttin a 5.3 in a 97 Z71, still gathering stuff, and I have the street and performance mount adapters when I pulled the factory mounts off of the vortec 5.7 I noticed the plates under them had a triangle hollow in them so I saved this to put under my mount plates if that helps anyone.

oh sorry i need to edit that into my profile. im located in thomasville,ga.Quote:

Im doing the swap right now actually and last night I went to go and mount my tranny and my worst nightmare came true, my motor was about 1.5" to far forward.
When I was looking at what designs of plates were best I could not find ANYWHERE that said "this one is stock location" . I finally stumbled across an obs swap and he used the S&P design plate so I figured well he did , so can I .
My truck has an nv3500 5 spd in it ... you can understand why I REALLY did not want to move my transmission .. my shifter would move.
So my suggestion is use the S&P design plate a picture of it is here ( LS1 Swap FAQs - LS1TECH ) and move the engine 1.5" backward of this.
Good luck
Thanks! Well I went from a 350/350 combo to the Ls1/4l60e. I dont know how much of a diff there is between the 350 and 4l60e as far as dimensions, but I used the original drive shaft. I wound up with about 1/2" more exposed on the drive shaft after the tail on the tranny. As far as the linkage I dont remember having to do anything to it.Quote:

Here is a link:
Vortec Gen 3 mount to early GM 3 bolt mount | Engine & Transmission Conversion Adapters - Advance Adapters
These look almost identical to the ones I made for my swap in my 92 k1500. It was so close to the same location that if the exhaust would have had the right collectors it would have bolted right up.Quote:

This is a plate mount that takes a Gen 3 engine and adapts it to the early 3 bolt frame mounts. The rear of the Gen 3 block ends up in the same location as the rear of the engine stock V8 being replaced.
Saw these on ls1tech. Dirty Dingo - Dirty Dingo
Think they will work for you? :chevy:
wow. 4 inches of play! they should. if the advanced adapters ones dont work im sure those would.
What I great idea.Quote:

The ones we talked about will be side specific and will adjustable from 2" rearward to 1" forward.
