Nothing... and I mean nothing looks cooler than a blown hemi, Dave.

An injected hemi might get close... but nothing says KMA like that picture you attached.

If people are worried about cutting holes in hoods, cut up a 'glass hood... you're painting the horizontals flat black anyway.

Also... on detailing a 6-71 or 8-71 case: I like the satin look, maybe with polished ribs. To me it looks more old school and workmanlike. For something a little different, you might consider painting the case body color and polishing the ribs (and the front and back) kind of like the Tony Nancy's old dragsters.
