Something you guys with 700r4/4l60e and custom exhaust might want to look at
LTX and LSXPutting LT1s, LS1s, and their variants into Third Gens is becoming more popular. This board is for those who are doing and have done the swaps so they can discuss all of their technical aspects including repairs, swap info, and performance upgrades.
Something you guys with 700r4/4l60e and custom exhaust might want to look at
So I won an auction with Hawks 3rd gen (camarohawk) for a used crossmember for a 4l60e , but instead this is what showed up ...
So naturally I thought maybe the picture doesn't meet the description ...
The ONLY thing I have to do to make this cross member work is weld a plate on to capture the bolt on the mount .. its already sitting on the member I just can't do it up proper because the bolt is just shy by about 1 inch..
This is awesome because I was just going to modify the 4l60e cross member anyways .. This is going to work soooo much better ..

bringing this back....how is this working out? I am looking to install one and was thinking of doing the same for a 700R4. However, I was just going to drill holes through the mounting sides to get access. Anyone done this?

The frame rails arent parallel so drilling holes to shift it forward wont work. The simplest solution is to weld an extension like he posted. I prefer to build trans crossmembers from scratch because they never fit out of the box regardless of brand/chassis

Angle iron and commonly available plate is typically made from A36 steel (36ksi yield strength), which is less of a concern in your application than the material thickness, the geometric configuration of your design and the quality of your welds.

Two 4' sticks of 2"x1/4" mild steel from lowes/HD is more than enough. Will have left overs for future projects and frame tabs. Weld sections together to make angle instead of sourcing it

I can't shift the transmission over, because it is already in contact with the new crossmember (I have already cut that portion off so it won't contact now.) Here's what mine looked like before I added the extra metal.

Yeah , I had to drill a new hole and cut the excess from between the new and old holes.
I wish I could show you a picture, but I already got rid of this setup for a T56.

Did you also have contact between the fuel/brake lines and the crossmember? That's the only other thing that I have to modify for this to work; and that's not to bad, IMO, considering this wasn't built for a 700r4.
