| I'd bet your gonna need 429 mounts. Also the bellhousings are different for the 429/460 from the 289/302/351w/351c.

| you will need different motor mounts the small block sits in differently than the big block will. I know this problem all to well i am having to look for motor mounts for a 351m because ford never put one in a 88 convertable. good luck with the motor swap. |

| I belive the 351m/400 use the same mounts as the 429/460?
Not to be to picky but why would you swap a 351m into anything?
