I was wondering if anyone had made or purchased a bracket that will allow a 700r4 to mount to a ls3 intake manifold along with the accelerator cable. I have searched forums all over and have not found anything.

Appreciate the help

 

Why not sell 700 & use 4l60e?

 

I already have a built 700 from years ago so I figured I would use that until it blew up

 

I was in the same boat as you. I had a new 700 with only 300 miles from bowtie overdrives and 2500 invested in it. I wanted to use it badly as well. But I am going to sell it and take a loss for a couple very good reasons. If the tv cable geometry doesn't get set up perfectly or newer engine makes more torque sooner with less throttle pull the 700 wont last anyways. Also will be way better having the ability to adjust shifts and lockup control. And lastly it will bolt up with no spacers or adapters. Just bite the bullet get a good used one.

I had the bowtie overdrives kit when I swapped my 87 monte. I used the stock 2004r with a flywheel spacer and the 5.3 to save $. The stupid thing never worked right, the shifts were either delayed or way too short. I tried adjusting it over and over but it never seemed to feel right. My buddy has the same kit with his ls swapped monte and he has the same issues.

 

If you get the geometry set right, there shouldn't be an issue. Regardless where the new engine makes power, unless it's unbelievably different, everything will work just fine.
The key phrase there is "correct geometry". and if you haven't checked into just how precise it should be, then you're going to have problems.



To build this into a stand alone bracket would take quite a bit of work and some decent skills but it certainly can be done.
Not only the distances but the radius must be carefully plotted.
