I would absolutely put the 409 in instead. The w motor is unique and I am putting a 348 in my '48 that I rescued from a '59 Impala that was heading to the crusher. I built my own mounts and it was a simple install. They aren't cheap though, so expect to pay more than a SBC will cost you to put together. I would do it again without hesitation and in fact chose not to put a fresh 383 stroker/blower motor I had on a stand in instead.

Here is the link to my build with it if your interested.
