The bling-free idea works for me: steelies, looking as stock & unassuming as it can and still run your target ET/MPH.
I'd lean towards a stroker SB, 904, not too much gear, cleaned up enough to be presentable but as original/unrestored as practical, subframe ties and put some brakes on it for that short top-end.
You could letter it with a sponsor: BigDad's Bikini Bar...Bigdad's Tople$$ Club...the driver's name could be "Daffy Duck"...maybe even his likeness on the tailgate...ah, but I digress...:)
