What engine for my new Town Panel?

402 stroker Poly.
That is the engine I wanted when I started hunting for one of these trucks. I couldn't find one with a poly.

I think a poly with tbi EFI and a 5 or 6 speed would be awesome. Wonder how hard it would be to mate a poly to a nv3500 from a Dakota...

Now I need to find a good Poly...
