Evening all,
Just 'pub chat' for now as I don't have the vehicle yet, it's in a crate. What Holley would you reccomend for a mild street 360? (That will initially be standard and tired...) With an intake, headers, cam etc.....
72 Dodge BVAN
Cheers

Probably no more than a 600 Vac Sec.
Maybe even smaller.
If you look at the CFM charts it points to a 550cfm unit....

A good mate of mine had a 500ci BB Dynoed.
With a 750 Holley and with an 850 Holley.
Amazingly it made more power with the 750.
Bigger is not always better.
Throttle response will be sharper with a smaller carb.

Honestly for your application I would seriously consider a Street Demon. Probably the easiest way to get a decent tune and good balance between power, economy and drivability

I want electric choke and vac secondaries,
Street Demon 625 has a nicer price tag.... A street Avenger is another $100 on top (570 or 670) would I even notice the difference between the two?
Is maintenance any easier on one?
Cheers for the swift responses,

A very good point Pete.
Forgot to mention mine has "cruiser" gearing , and would be interesting to see how it performs with a livelier set up out back

Check the link and go to one of the carbs, in the overview there are tons of links to tests from magazines etc, brochure etc. It's like a modern thermoquad, brand new design. Look at the Holley recommendation but I'm sure the 750 would be equally OK

the aussies swear by what they call a holley 465 for torque and street manners. i.e "look how quickly i can tow my sizable boat full of bilge up the slip-way with my cool mopar truck" can't tell if Bananarama! up or not....
i don't think they are made anymore as a Holley 465..
believe this carb lives on in the US with a 500+ CFM name as a holley style clone by one of the race carb manufacturers
its not a bored out aftermarket 390 it was a proper holley model, i know they exist just never held one in my hand
