[Healeys] Converting from HS4 to HS6 carbs

[John Spaur]

It’s not that I want too. Burlen S.U has not shown HS4’s as being available on their website for over a year now but the HS6’s are. I had emailed them several times but they don’t respond to emails. I finally got around to calling them and they said they had the parts and could build a set. So, I placed an order.

I can confirm that converting my first 6 cylinder race car, with a standard MkII engine, to HS6 carbs without any other mods improved my lap times at our home circuit by absolutely 0.00 seconds ... seriously disappointing 😕😕

John, have to ask why you'd want to do this.  I'm not Edd China--or even Ant Anstead--but from all I've seen and heard just adding greater air flow capacity, without other mods--cam, headers, etc.--does more harm than good.  

I think I read somewhere that Geoff Healey thought BJ8s were 'over-carburetted' (maybe why headers supposedly add a few HP without other mods).

You will need H6 intake manifolds or machine out your HS4 manifolds. I am not sure about the linkage.

If I change from triple HS4 to triple HS6 carbs can I just swap them out or do I have to change the linkage and other components?
