Hey all, recently went and picked up my first classic mopar. It's a 1966 Belvedere II with a 440 out of a 72. Rebuilt, Mild cam, steel crank, 0.30 over, shaved heads runninf 10.5:1 compression, all according to the old owner. (All the info I have until I can get ahold of the engine builder..)

It was supposed to be road ready and a good runner. Runs ok but pops at 3/4 to WOT and wants to die when in drive. Thinking it's partially a tune up issue, but after inspection when I got it home I found that they put the original grimey leaking carb (thinking thats part of the issue as well) with the stock intake back on, and I'm looking to get rid of that for something else. Ive found a Weiand high rise intake mated with a Holley 830 double pumper locally that this guy had on his 71 charger for around $400 Canadian. Apparently "De tuned" for street use.

Anyways im totally green with carbed vehicles and my questions are:
Is this thing suitable for what I've got? Ive tried reaearching it but cant find much on this specific set up.
And has anyone had a similar set up that can offer some advice?

I know I'm going to run into possible issues getting the throttle/kickdown to hook up properly, but hoping someone had had a similar set up and can offer a little advice before I make a decision on this thing.

I'm an electronics specialist on newer vehicles and carbed stuff is totally new to me, so please excuse my questions if they seem very basic or easy lol

Thanks
 
I'd consider fitech or Holley sniper for not a whole lot more money. Especially if you are an electronics guru
 
For someone up on modern auto electronics, dieseldazzle sure makes a good point. As for the carb setup, depends on which Weiand it is and the 830 DP is probably not the best choice for a mild motor.
 
For street use I'd go with 750 with vacuum secondaries with some sort of dual plane. I chose the RPM. $400 CAD is pretty cheap though. I'll also agree with the top two posts. If you are comfortable with electronics go for EFI.
 
Based upon the description of your motor, I would suggest a dual plane intake manifold. You can easily tell & one way is to look down the hole(s) where the carburetor bolts up. The left & right bottom of that hole(s) should be at different levels....one "floor" is higher up than the other one. That's a dual plane intake. Single plane intakes are for high rpm racing (both "floors" at the same level).

Also, a double pumper anything is WAY too much carburetor for your engine. I would suggest a 3310-x 750 Holley vacuum secondary, a 600 cfm Holley vacuum secondary (cheapest, good mileage, a tiny bit small for your motor), or one of the Edelbrock/Carter carburetors. I would "ballpark" your best carburetor size at 650-750cfm.
 
Thanks for the input guys.

I can appreciate what you guys are thinking, electronics guy should go Efi. I probably could, but I deal with fuel Injection and electronic headaches all day every day, it gets old fast haha and want to stray as far from that as i can with this car. Wanna stick to the old school stuff and learn that the best I can before mucking around with efi.
 
The edlebrock performer RPM is a really good intake for the street and should not require much in the way of modification on the linkage, as for a carb, I would suggest a 670 cfm Holley street avenger, it has an electric choke and I have used this carb before or the Quickfuel 650, it also has an electric choke. Both are great street carbs.
 
don't forget to check for hood clearance..... I'd put a eddy carb on a low dual plane and drive the wheels off it
 
I'd go with 009&purple , but I'm old school:).
 
I have been reading on the 625 Street Demon carb made by Holley and it sure looks good and simple. I also have a new in box edelbrock 750 electric choke and a Holley 750 DP with the Holley electric choke kit. DP are better for a manual transmission. Still leaning towards Street Demon.
 
I agree with above that a DP on the street is too much for ur setup
 
slap on a 750 Edelbrock and be done with it.do you really need an intake?most low dual planes are not alot better then the stock stuff.just lighter.750 is really close to the factory performance carbs of the day and easy to adjust.keep it simple if you are not looking for a bunch of power.
