302 to 351 m info

hi everyone.i have a 1989 mustang 5.0,and my friend has a pretty pumped up 351m that he said he wuld sell me for 800.its rebuilt and runs good and has alot of performance parts.i know i will need to change the motor mounts and the bellhousing on the tranny.i know getting it in the car wont be a really big problem i think(any replys to that comment welcome)but mostly i was wondering about the tranny.will i be able to use a t-5 tranny or will i have to get sum other tranny.im really hoping i culd just use a t-5 with the different bell housing.any info would be very helpful.thank you
