the answer is yes. a lot of the parts are interchangeable. for instance a fe block with a 4.05 bore can either a 360 (using a 352 stroke), a 390 (using a 3.78 stroke), or a 410 (using a 428-3.98 stroke). it's all pretty much what you want to do. i am personally building a 410. speaking of which, denny, do you know any good websites about these engines. also there are some pretty good books out there about fe's and the interchangibility. i believe ebay has some right now.
