a 833 conversion

What I said was it didn't touch with the engine just sitting but did when it was running and moving in the mounts.

Putting a small dent to clear the boss is not going to have any structural impact on the cross member and may make it stronger. Ever notice how the floor panels are formed with ridges? It's to make the panel stiffer.

Folks cut the center section out of the cross member to make clearance for A500 or A518 trannies and weld in some flat stock to tie it back together all the time.

When i put my A833OD in I didn't realize that it would touch until the first time I drove the car. At that point it was easier to go inthere with the tip of a sawsall blade and nip it off or I would have dented the cross member for clearance.
