2.3 with c4?

i just got a stang parts car, someone put a 351 in and twisted it. anyway the tranny is fine, and someone told me it was a c4. do i just need a different bellhousing to bolt behind my 2.3? it has the old a4ld now and i think a c4 is better and more reliable isnt it?
any help?
 
Don't know about the bell housing, but the c-4 is DEFINATELY a stronger tranny.
They were also used in old 5.0s so you should be fine w/ that behind your 2.3.
