SU H6 and HS6 carbs

[Hap Waldrop]

Excuse my ignorance, but what Triumphs came with H6, or HS6 carbs, or do folks put these carbs on Triumphs that didn't originally come with them. The reason I ask, is we run twin HS6 carbs on the MGB race cars, and I made these before and will be making a new run pretty soon and would like to see if the Triumph owner have a interest in such apiece. Thee are billet aluminum velocity stacks that have a 3.5' OD on them ,and there forth designed to run the KN RU-4410 universal cone air filters. We're changing the original design a little, and getting rid of the OD radius on them as they were originally designed to run inside a cold air box, and losing that outside radius would work better with the KN filters.

Hap, the TR6 uses Zenith Stromberg Carbs.

TR3/3A/3B and early TR4 came with the H6. They were replaced on the TR4 by Z-S CD175s, but later TR4As got the SU HS6.

But there are a few people out there that have switched to HS6's in their 6's

What is the cost of the velocity stack and when will they be available?

Just an FYI: Joe Alexander is reproducing stacks as developed by Kas Kastner and used on Triumphs:

I waiting on a volume quote, so I don't have pricing on them now, but will post here, as soon as I do. The deal with these stacks vs others is you can use the KN RU-4410 air filters, the issue with horns like Joe sells, is that require a unique air filter arrangement often times with a air horn, people use foam socks, not the best solution, so these are nice with the KN RU 4410 air filters, because you can remove you air filter in about 10 seconds, and short radius stack flow better at top end that longer horns.

Here's a pic of my vintage MGB race car's engine bay , you can't see the stacks in this photo, but more importantly you can see the fitment of the KN RU-4410 air filters, it doesn't get more worker-friendly than this.

Did you happen to get any of these stacks made? That combo of stack and K&N filter would fit my set up perfectly. Thanks.
