Joker, The 302 will bolt in using 89 Tbird 302 mounts. The C-4 will fit but I believe you'll have to length the drive shaft (Imay be wrong there, don't know) The big problems will be wiring past the computer (by passing it), changing the pulleys on the alternator and ac compressor to go with the Granada's v-belt drive.,exhaust, etc. But it can be done.
