OK, how much did he engine cost?
I haven't seen a hemi worth using listed for less than I have in my engine, air cleaner to pan. And that's done in the car and running 11s.

Look at this hassle and $$$ for 250 wheel horsepower. LOL
I'm not saying it isn't cool or different (if you're into that) to do a new hemi swap, I just can't see spending the money when you can have a higher horsepower conventional small block for a LOT less.
