Holley Sniper with the Hyperspark distributor would be very cost effective. You could sell a race carb and a MSD setup and pay for most of the Sniper kit. The Sniper is good for up to roughly 700 hp. You'll need a good high pressure pump and a return line.

The Sniper (buy the Super Sniper) has data logging capability so you can review your runs. The Hyperspark setup lets you control ignition timing with the computer so you get built in start retard, high speed retard, and the ability to build a custom timing curve.
