What the chance of 300 fitting in a Falcon where a 172 use to live? Will the flywheel/bellhousing bolt up ?? The car has 3 on the tree now. A 4 speed and larger rear end (Mustang) could be added if needed.I know where a real cream puff car is and would like to be better schooled on this before I jump up and make a offer on the car..Always building something in my head..OL'SCRAP
