4L65e into 71 Chevelle I have acquired a 6.0L Lq9 that I'm going to put a carb on, a 4l65e also came attached to it and I would like to install that as well, however I am really wanting to do this without cutting the trans tunnel. I know it can be done I'm just looking for information on what motor mounts and cross member have to be used to do it.
Thanks!
Thanks!

An LS engine with a 4L65E fits easily into a 2nd Gen Camaro without any cutting; I suspect the larger Chevelle has even more space there.
This is the wrong section for your question.
There is a "Conversions and hybrids" section.
While I have never visited the Chevelle forums which likely have swap info, you might also try the Gen2 Camaro forum www.nastyz28.com in the section "High Tech Retrofits". IMHO, the Camaro forum has faster replies than most other forums and many Chevelle and Nova owners therefore participate.
The likely "issues" with your swap will not be the transmission, but selecting an engine oil pan than doesn't hit the subframe crossmember and doesn't interfere with the steering linkage. This forum has a ridiculously long thread on oil pans for any swap: https://ls1tech.com/forums/conversio...-oil-pans.html
A G-Force crossmember from www.crossmembers.com will take care of the trans mounting.

Even if you don't have to cut the tunnel, you will need to beat it in places with a large hammer unless you mount the engine ridiculously far forward (don't even know of an oil pan that would let you as far forward as it would need to be).
I used LH8 pan (hangs low), old style BRP engine mount plates, stock SBC engine mounts but moved the frame stands to where the engine wanted to sit, and the stock crossmember in the frame holes for a TH400/700r4. The tailhousing of the trains needed 1" spacers between it and the trans mount to get a good driveline angle.
Large hammer on the firewall around the bellhousing took care of the rest.
