With a heavy street-driven vehicle, you will want tons of torque, not necessarily a lot of hp. Here's a recipe that I worked up on the DynoSim software a couple of years ago that may be of interest.....this is a pump gas-friendly build.....

400 block bored 0.030" and zero decked to the piston crowns, align-honed or align-bored main bearing bore.
The stack of parts used in this build will total 9.008" (piston 1.433", crank radius 1.875", rod 5.700"), so cut the block deck height to 9.008" for a zero piston deck height. Using a 0.039" head gasket thickness will yield a 0.039" squish. Use only a gasket that is designed for a 400 block, as the gasket MUST have steam holes to match up with the steam holes in the block. Here's an example....

6" rods will push the piston pin up into the oil ring land, adding complexity that you don't need.

Air filter base and lid to house 14" x 4" paper element. The motor MUST be able to breathe. Snag the correct length stud and a wing nut from your local Ace Hardware. OK to stack two 14" x 2" filters.
Long-tube, tuned headers, 1 3/4" primaries. Use an "X" or "H" pipe before the mufflers.

Get on the phone with Dart and counsel with them about the initial, centrifugal and vacuum ignition timing for this combo. Oh, and I absolutely agree with Mr. P-Body about the cooling system.
