With your 465 Holley, have you done any head work to the motor to accept the extra fuel from the holley?

I have been told by an ex- mechanic mate, that the 465 Holley may flood my motor???

I am keen to know whether you do get more noticeable performance with the 465???

Paul, You have to throw a pretty well large jetted 465 to flood any engine along with a stuck needle and seat,
Most Mechinics who think that do not not know how to tune carbies properly.
The 465 has smaller primary throttle blades compared to the 350 and larger 500 of course, so with the right jetting and power valve you can and should be able to tune them with fantastic economy and power when the secondaries are on.
Just as Smooth mentioned and Stingray, I have fitted lots a holley, tuned correctly they run smick, There are plenty of situations where others get the wrong or incorrect advise, and over carb there engines along with lots of other things like, wrong camshaft selection to manifolds to radical compression ratios, all these factors come into the equation when choosing a good carb setup. Not just for outright performance but for good drivabily and economy.

Guys after many years selling and running Holley 4BBL carbs on Holden 6's the pick of the bunch is the Holley 450 cfm with mechanical secondaries. It's part number is List 9776 (you find this on the choke venturi area). It is a square bore without choke (but can be added). These are basically a 350 cfm on the primaries with the extra punch available on the mechanical secondaries.

It was common for me to sell two of these to sit on top of a tunnel rammed 253 or 308.

These are a performance carburettor as apposed to the vacuum secondary 465 cfm verities. The mechanical secondaries come in at around three quarter throttle.

If you are buying new - check these out.

Regards, Smooth

gday paul

I think its all been said, but would like to reitterate

im running a 186S bored out 30thou, with very minor port work and a redline manifold
the initial problem I had with my recond 465 was flooding, and no wonder with standard jets and a vaccum secondaries

since having it changed to mechanical secondaries and smaller jets - Its unbelievable the difference it has made

performance, response and still pretty economical.......for a worked 6
on the return leg of our nationals trip in june - Forbes > Adelaide it cost us 185$ in fuel, not bad for a 1000+k journey
also idles nicely with the 35/75 cam,and electronic ignition etc
have also owned hot sixes with 350holleys, thought Id give the 4BBL a go - no regrets

cheers stinga

but in yeprat's case too much info he only wanted to know weather we thought a cable would be better than linkages

Have any of you guys got photos or more details with regard to the cable/ pedal setup cause I am also going down this same road.

Hi PEARO hope this helps.
I like this mod cause it uses the original pedal and you can run the cable through the bulkhead with the choke cable.
Think its off a 80s model, grab a spare and keep it in the boot.

Stingray/HEMI,

I am having trouble getting the carby (2 barrel Holley) to reach full butterfly travel (fully open) was wondering if I need to extend the pedal lever ( where the cable links to the pedal) which would give me more travel of the cable and allowing the buttefly to open fully. Did you guys have trouble with this.

Cheers
Rob

gday rob

dont recall having much trouble when Hemi did my cable, but i was working on somthing else so only saw the before and after
the only thing i could suggest is making sure where the cable attaches on the throttle lever-of the carby, that it is as far to the left as possible
-which would also alow the butterfly to open more also
thats if yove got the same set up
the part im refering to is the brass cable holder thingy on the throttle lever - above pic - you could drill a hole further over and refit or get a new one
sorry im no carby expert
try sending Hemi a pm, he may be able to help you out
