Why not truning it into a HemiCuda clone, only with something like a 572 pumpgas Hemi in it? Best of both world...hemicuda clone and single digit pumpgas dragweek racer as you mentioned.

Can be done, my street/strip car was a full weight streetable Challenger powered by a 528 pumpgas hemi having no problems running mid 10's while having a relatively mild flat tappet cam in it. More cubes and a roller would have given 9's. It's now al going into a lightweight race-only Challenger shooting for low 9's.
