simple? $550 for a scorcher distributor , or $300 for a half faulty hyperpak ignition computer. $239 for a redline twin dcoe/dhla manifold, about $600 for used carbs, throttle linkage kit $100-200. I just bought a set of bigger chokes, idle jets, emulsion tubes and idle jet holders for my dellortos for $200... and that doesnt garauntee it will run well through the rev range still..
if you wanna keep it simple get a loom and an ecu and plug everything in.
p.s. forgot $70 for filters and $250 for trumpets and filters which the filters didnt even fit in between the brake booster.
