Howdy,
Never heard of this carby before - can anyone give me a recomendation as to what they're like - may be destined for the junkyard special 186 to go in 'The Hornet'. Am also waiting to see a 390 come up - any reason these seem to be rare...? Would the 390 really be that much better than a 465 for a stocko 186 with a 4bbl manifold?

I had a 450 Holley for a while. They are OK but not great. They have mechanical secondaries, use metric (Weber?) jets and, back when I had one, they only had one power valve available. It was a fairly good carb but not very tunable and no good with a lump

I have used 450 (4360)holleys on 6 cyl reds and on 253.They are great economy carbys. (if you dont use all 4 barrels all the time) Has Qute said they have mechanical secondaries and they do not have a secondary fuel pump like normal holleys, so sometimes

I've got two 465's in peices - both missing metering blocks & I've got a 600 complete but needs rebuild. Is the list number the one printed on the primaries intake, facing forward...?
I'm assuming even with jets changed etc the 600's metering block wil

would a 390 or 465 four barrel be better of worse than triple 1 3/4 inch Su's on a warm/mild 6 cylinder red 202.
what might the performance and economy figures be between the two types of carbies? which of the two would be more reliable?

The little 4 barrels would take less maintenance than the triples and, in my experience, be just as good from about 3 to 6 grand (depending on cam choice). The triples will give better low rev smoothness and response.
Agin in my experience, the Holleys

thanks Qute
so my "weekend" HQ would be ideally suited to the triples given that it spends most of the time down in lower rev range, am i correct in thinking that?
the engine has a yella terra stage three head and a 25/65 cam that works best in th

It's really up to you John. If you are willing to do the extra maintenance the triples demand, they would probably suit your requirements better.
Just make sure you get a matched set OR you get them all properly rebuilt or it will be impossible to tune

Beige Hornet.the list number is the one printed on the primaries intake. Carbys in bits aways means more cost overall.I have cross fitted metering blocks. But with out the original to match it to it makes it harder to make sure you have the right metering

hi ya HQ ss
the kingy is running a jetted up single stromberg. in day to day running it seems ok, however when the revs are increased to overtake or accelerate up a hill the car begins to cough as it need more fuel, or so i have been told by several

Thanks hqss, I think thats the understanding I'm finally comming to as well. Just a bit frustrating having heaps of bits & having to buy more, when I'm on a budget. That being said it's probably better to 'do it once, do it properly'. Does anyone have a c

Sorry The Beige Hornet Im in WA I can not help you there.
John in your rebuild have put a new fuel pump on and or had it pressure tested.It is just that about 70% of carby jobs that are sent to me end up not being the carby at all. With your electron

Hi John,
Unless you are running a VERY small Strommy (or there is something REALLY wrong with it), you shouldn't run out of fuel unless you are spending LOTS of time in the upper rev-range.
I'd agree with HQ SS, it sounds like you have another issue

hi guys and thank you for your ongoing assistance, the hq is just fine in everyday driving when the revs are say under 3,000. But when you start reaching the higher revs she coughs and starves for fuel, this is most noticeable when the car is under loa Edited by user Friday, 17 November 2006 1:06:09 AM(UTC)

Hi Guys.
A small carby will not 'starve an engine of fuel'. A carby supplies AIR, with fuel mixed with it. If the carby is too small it just means it won't rev to its maximum available, it won't starve & stumble. It's just like holding it at half throt |
