What carb is best for me

[Onewickedchallenger]

I have a 528 hemi I bought to put in my 70 Challenger RT/SE. I have a 727 auto transmission that will be behind the Hemi. What  size carb do I need. This Challenger will be a cruiser. Not a race car, I am thinking 850 holley with vacuum secondaries. What is a better carb?

Thanks

an 850 Holley is a perfect choice.

If you like to blast down the road occassionally, I'd go with mech secondaries.
I have an 850 Holly DP mech secondaries on my 496. went with annular boosters for better
fuel atomization on the street. Jets are 84's front and back.

what stall do you have, rear gears, cam spec, intake?

you could use a bigger carb but an 850 will work. I'm using this carb on a 451" and it works great. Best carb I have ever owned so far!

Quick fuel / Proform , I agree with the Mechanical secondaries & you may want to look at the 950 CFM , Mancini has the best pricing

I agree. 950 would be better on that engine. Those Hemi's are deep breathers.....

EDIT:

One other point to bring up here concerning carb size on any given engine.  I have always used the old two times the cubic inches rule. This works for small block, big blocks, and might be a little undersized on a warmed up Hemi. In your case, 528 CI X @ = 1056 CFM. So 950 is probably a little small on your set-up. In my opinion, and 850 will kill the performance of that big 528 Hemi. I am running twin 750 HP's on my 528, and it runs great.

THANKS Men, I will look into a 950 carb. It will have 3800 stall, inline stock manifold, gears i don't know just bought the challenger.  This is a crate engine, I bought it from a guy who did not know what the specs are on the cam were.

Thanks

I think theses are the cam specs.

hydraulic flat tappet
292 advertised duration
.524/.543 lift

Get a big one!!! 950cfm at least.

We've been around this block before but it really comes down to head flow, cam, stroke, compression and now much you will rev the heck out of the motor.

True dat.  Nothing worse than a big cube Hemi that can't pull hard on the big end. That's what they do. Let it breath......

Ditto the 950 suggestion.

Yup BIG BIG - I run a 1000 CFM HP Holley on my 500CI down the track and on the street. Performs very well on the track as well as reasonable manners in Friday afternoon rush hour traffic in 30 degree celsius on Deerfoot Trail in Calgary (nasty)

for Cruisin, 950 is overkill.
850 hp NASCAR engines use an 830cfm carb.
if you were a quarter mile drag racer, crossing the line at 6500 rpm, then maybe the 950, but even then,
it may only net you 10 more hp.
Much better throttle response on street with the 850, and annular boosters.
