UPDATE - Looks so good but ya can't shut the hood

The 70-71 air cleaner is already pretty flat or low looking IMO. Oh well time for a Super Stock hood right? :)
I like the way you think.
O.P., You could take a page out of the '68 Super Stock Hemi A-Bodies and put 1'' aluminum spacers under the frame between the
K-member and the frame to lower the engine in the engine compartment, and no one will know unless they look!
Cheap and dirty...
