1940 Ford Modular Engine Swap

I just picked up a '40 Deluxe Convertible project - stock frame, front & rear suspension, no engine or trans. Body very straight with all the trim and stock bits and pieces.

My build target is a restomod type, stock body and paint, wide whites etc, with IFS rack & pinion and parallel leaf rear - 9" and since it will be a driver I want a late model computer controlled FI engine and overdrive transmission. I have seen several LS1,3 & even a 7 with 4L80E transmissions swaps in 40's that look very good. Nice fit etc.

However, I would really like to put a Ford in it.

I would like a 5.4 DOHC with an AOD-E or the new Boss 302, but I really dont think there is enough room between the inner fender panels to accomadate the wide valve covers of the DOHC. I have seen a couple of '40's with 392 Hemis that "just" fit maybe 1/4" clearance on each side. A friend of mine put a 4.6 DOHC in his Model A told me that the 4.6 was about 3 1/2 wider than a 392...

So, has anyone seen or ideally done a 4.6/5.4 3 valve SOHC engine in a 40? The nice thing about the 3 valve was that it was used in almost all of the 150 trucks and SUVs so it should be fairly easy to find a reasonably priced low milage donor.

Any thoughts, ideas, suggestions - about the only thing I wont consider is a flathead - been there, done that - didnt have a great time...
