LS and T56 with stock crossmember?

For those of you that have a T56/LS combo: Did you have enough clearance to leave the stock crossmember in place? I asked this question in my build thread but got no response so thought I would try the LS Swap specific forum as well. More details on my setup and photo here:

Mine originally had a 3 spd saginaw so no rear crossmember so i just bought a cpp tubular one. I think it was less than $100. Works great. Of course the nightmare of trying to remove your original one with rivets might be what you are trying to avoid....

Thanks. Just to clarify, I have an aftermarket crossmember that will be used to support the rear of the T56. As you implied above, i would prefer to not have to also remove the stock crossmember which is near the bell housing and rivited. Full details and pictures are in my build thread linked above. It looks like it will clear but just hoping to get confirmation from someone who has done it already to be sure. thanks!

I didnt try to fit the transmission that way. I removed that forward crossmember. It was a pain to remove (ended up nearly cutting it in half to work it out) but it was worth it. It really makes exhaust routing a lot cleaner as you dont need that kickout on the driver side any longer.

Re: LS and T56 with stock crossmember?

It is a bit of a PITA to remove all of the rivets with the cab on the frame, to get it all removed. I always recommend removing the bellhousing crossmember if you are not going to be using it to support the original bellhousing. It is so much easier to work on your truck with it not in the way if it is not needed. I have seen some guys just cut it off flush with the frame rail and leave the rivets and small pieces attached to the frame.

Looks like I will likely be doing exactly what you an CaptainFab recommended. Last night, when test fitting my Throley headers, I noticed that the drivers side header collector points directly towards the stock crossmemeber. There is no way I can use those headers with the stock crossmemember still in place, so I guess it is coming out! I might start by just cutting it out flush like CaptainFab mentioned.

Thanks for the advice guys!

Any chance you recall what shift position you used on your T56 (forward, mid, or rear)? I was taking some measurements on my newly acquired T56 last night and I fear the shift position is too far forward. The vendor put a forward shift kit on it because I have a bench seat, but I think it will cause me to have to reach really far forward and might even interfere with the dash. Thanks.

Thanks for the reply. Not sure I understand. Did you modify and relocate the stock crossmember to support the T56? Thanks.

I have the same set up. I used my original automatic cross member. Got rid of the lower plates and it works perfect there were even holes in my frame already there. I did have to shorten my drive shaft. I suggest going with captain fab for the hyd clutch set up, I have it and it works Perfect. This is the easiest and best swap I've eve done. It's a lot of fun to drive
