Are there any issues hooking up the fuel lines and vacuum line for the distributor like thread pitch. Reason I asked, when I was looking at the Summit site, when you brought these Holleys up they listed some fittings like an AN6 with an inverted flare as something folks bought at the same time.
thanks again,

You're existing fuel line fitting going in the carb will fit the Holley, it's up to if you want to bend up a new line or just cut the old one and hook up rubber hose to it. For the vacuum line there is a port on the right side of the throttle body but I prefer just to use the vacuum straight out of the fitting in back of the intake manifold. I first did the Holley conversion back in 1975 at the age of 15. it was so simple all that was needed to adapt it was basic GM to Holley 2bbl adapter since the 305's intake base shared the same dimension as most other GM engines equipped with smaller 2bbl carbs
