"You'll drown it in fuel!!!!!!"
"The computer chart says... cfms's!!!!
"Blah Blah Blah BLAH !!!!!"

I've heard it all, but the wind is out of my sail to continue the beat. I simply walk away. I say "ok", then smile. I will charge to explain it anymore. LITERALLY! You will PAY me before I go rounds again and explain it to you. LOL :D

Shelby, now there's a name. A recognizable name. A name that's tied to performance. What did he know?? Obviously, not much!! Because he put over 700 cfm Holleys on 289's. Yes, if you bought a Shelby 289 Mustang, you got a over 700 cfm Holley.

LOL, I run a 750 TQ on my 273. I know, that's cheating... Never ran better. Put a HP 440 AVS 750 on my brothers 289, and he told me to sell the Holley 600. Did the same with a friend at work who had hot 289, turned a quick car into a monster. Some people are too "smart" to help.
 
Both are air demand carbs....put a 750DP on it and you may overcarb it but a DP on any car has to be carefully considered.

Never happen. I sold all my Holley stuff decades ago. I won't run one. I just drive around with a big smile on my face.
 
That`s if you take this guys info as gospel.
4160-C seems to keep coming up as 600 cfm
4160 is a model number indicating a non mechanical secondary Holley carburetor. Holley makes 4160s from 450 all the way to either 800 or 850 I believe. The list number is what narrows it down further.
 
I'm really likin the Quick Fuel Holley style carburetors. Very affordable and they have adjustability that only some other higher end carburetors come with. The one on Vixen really screams.

I thought 4160 was the spreadbore family designation and 4150 were the square bore carbs, not individual model numbers. Think there are DP and vacuum secondary in both families.

No sir. The spread bores were 4165 and 4175.

4150 uses the metering block both primary and secondary. 4160 only uses primary.
 
I had a Holley 800 DP on a 289, 4 speed, with 4.10 geared 8.75 Mopar rear,

Super Stock springs with pinion snubber. Don't know any hp or torque but I could let the clutch out just above idle and just start rolling, then stomp it to the floor and it would pull like a 440. Then at about 6500 rpm, those L60s would bust loose. Ride it out until it stopped spinning, at 8000rpm yank 2nd and repeat, then chirp the tires hard in 3rd. I hung out with mostly 440 Mopar a-body drag racers and even they were impressed.

I love that car

It was one of my all time favorites. A friend of my has owned it for many years. It has a different small Ford engine, a different 4 speed transmission, and now a narrowed 9" Ford rear axle. Magnum 500 wheels all around.
 
Throttle response can suffer from too much carburetion too fast it's a velocity thing but if you have enough gear ratio to allow the motor to wind quick enough it can handle a lot of carburation Mopar race manuals called for an 850 double pumper for a single plane for Max effort for a 340.
