You can swap all the 289 stuff to the 302. The timing chain cover, water pump, balancer, pulleys...etc. The exhaust will also swap over.
If u were asking what else you can put in there, a 351w will go in, but it is suppose to be a tight fit. Will take different exhaust most likely and I think you may need some different motor mounts to lower the engine in the bay, to clear the hood.
