HQ Quadrajet

As Paul says it suits later HQ, early LH plus early HJ manual 308.

The blue motor carbs are better for 2 x reasons but no compelling reason to change yours:

1. Primary metering rods are adjustable without pulling the car apart.
2. If you change valley cover to Edelbrock or KC the choke mech is on the carby; early carbs have it on the manifold (divorced choke).

Thanks Byron.

Someone told me the newer carbys were significantly better but if those are the major differences Ill reco mine. It still has the std holden manifold on it. I will chnage the auto-choke senser to an electronic one as the heat one wont work as I think the pipe went to the manifold and I want to keep extractors on it.
