Ideal HyperPak setup???

Others will chime in, but I think the first learning step is terminology:
HyperPak was a factory performance package that consisted of their manifold, that was later sold to Clifford (if memory serves), headers, and larger carb. Legit HP parts are expensive and hard to find.

With that being said, there are a few different companies out there offering intake and exhaust upgrades. Clifford, Offenhauser, and AussieSpeed in the intake side, Hooker, Clifford, and some others in the headers, + any available 4 barrel carb of your choosing.

The ideal combo depends on you vehicle and your intended purpose for the car. Daily driver, Sunday special, Speed and performance? These will enable the /6 pros to make recommendation for parts and configurations that will work for your use.
