Re:GT/CS 289, engine swap

As I understand it, the biggest issue is the shock towers on a 390 are different than the small block, and these would need to be replaced to make this swap. If you want greater displacement and an easier engine swap, consider a 351W and go with a stroker crank...407ci!!! The 351 fits the engine compartment like a glove and there are many hi-perf parts available for this engine. Just a thought.
