I am finally getting all my ducks in a row to get the LS swap on my 65 4dr moving. Its great that CBR and a few other companies are making swap parts for our novas. The only big thing(and it's not too big) that I know I need to fabricate will be the transmission crossmember.

I plan on using CBR mid length headers with their engine plates. If I was using a 4l60, i would happily buy the CRB crossmember. Unfortunately, I know I will need to fabricate a transmission crossmember as I will be using a 4l80e. I was wondering how much drop the CBR crossmember uses but realistically, I am just trying to figure out what the final angle would be so I can just work backwards. Any help or advice would be greatly appreciated. Thanks!

I believe the angle should be 3 degs. down at the end of the tranny.

It's my understanding a 4L80 will require tunnel mods.

That’s what I’ve heard, but it doesn’t sound like they will be too extreme. I know it usually hits where the cooling lines come out of the trans. I’m using low profile banjo fittings to give me more room.And I’m pretty sure I’ll never break a 4L80e.

Chuck will sell you the cross member that has not been welded together so you can weld up as you need.....
