Engine to transmission supports

They serve a purpose and I always use them.I have seen broken bell housings and the bottom ears broken off of the block too.
Why only believe in half of the engineering?
And yes Rainy length is determined by trans
904 or 727 Merry Christmas. :)

Yep, a racing buddy had a serious vibration going down the track, because he was not running these supports, there's nothing for the bottom half of a 904 or 727 to bolt up to. He installed a set and shazaam no more vibration. My trans builder insisted that I run these.
I've only run a 904, but it sounds right that the 727 supports would be longer imo.
