Thanks

Get a small four barrel manifold and make an adaptor plate to use a Quadrajet's two primary throats only. Absolutely brilliant solution.

Forget the Holley - that will cause fuel starvation issues on hills, flat spots you can't tune out and you'll think there is a hole in your fuel tank. If you have a 2 barrel manifold ready to go, stick a Webber on it. Smoother. Better economy and won't conk out hills.

If as mentioned you still have to buy a manifold, find a 4 barrel manifold and go with the quaddie primaries.

Ok.....thanks Gav....So which Webber?

Now that's a good question mate - we used to fit these a lot - you may need to make an adaptor plate by the way - but we used to go down to the wreckers and pull them off any car that had one - and I can't think off the top of my head which ones did....

I'll have a think and a search and see if I can find out.

from my research I have come across the 34ADM as the weber to suit the holden 186

There is one ebay at the moment for $30!
