Hummm, considering that it was a option in '74...theres no difference in the engine bay dimentions and all smnall blocks minus exhaust manifold and possible intake/air cleaner hight differences, I'd say yea! This will drop right in.
If this were a /6 car, then the trans daprt swap mounts would be good to get. If it were a 318 car,, a driverside engine mount would make tings easier.
Keep in mind the 360 is a external balanced engine and the other small blocks are internaly balanced.
