I'm using Shumacher mounts on a 340 block.
Ding! Your post caused a bell to ring! It just occured to me...my engine/K frame and suspension are sitting on a home made cradle where the K frame isn't level. Of course that would affect the trajectory of the steering shaft out of the steering box and may have caused the clearance issue.
Thank you for your post and confirmation that it will work. Peter Bergman was surprised about the fitment issue also!
