Big small block
If your spending that kinda money I would talk to Bill Richardson or Dale Chenoweth and build a old school hemi with a new block just rough #'s but a 540 cu. in. made 877 hp and 776 tq with a cross ram and vacuum secondaries. Mike Chenoweth (Dale's son) is also running a hemi not sure what combo but he is running a 10.10 1/4 mile in a 4100# (i think super bee)
