Default 73 challenger 318 hop up

A buddy of mine just picked up a 73 challenger with a 318/727 combo. It has the four barrel intake/carb. He wants to get the most he can from this set up but keep it reliable. He also does not want to tear the engine down . I told him to go with this set up. Tell me if I am on track.

Performer intake
600 Holley/edelbrok
268/454 Comp cam
Hooker headers
2.25 dual exhaust with x pipe
2 chamber delta flows
2400-2600 stall
3.23 to 3.55 gears
