1. EI, just do it.
2. Smallest plenum and shortest runners you can find.
3. 600 Vacuum secondary carbs. take 'em apart and make sure the jetting and power valves are matched. Make sure you have backfire protection for the PVs.
4. Get a good linkage and throttle. I used a /6 throttle cable, but you are going to have to come up with a good kickdown.
5. Clean out any carbon in the engine first, then run as much initial timing as it will take without detonation.
6. Figure out a good air filter and fuel lines. Please no cheesy pep boy chebby stuff.
