Hello, i am having my 77 440 built at a locale engine builder. Here is what i have so far:
Block is bored 30 over.
i have this cam for it. Comp Cams Xtreme Energy XE268H hydraulic flat tappet cam K kit for 1959-1980 Chrysler 383-440 engines. Hydraulic flat tappet.RPM range 1600-5800/Advertised Duration .268 int .280 ex/Dur @.050; .224 in .230 ex/ Lift .477 in. .480 ex with 1.5 rockers.

Heads are Edelbrock E series Combustion Chamber Volume 75.0 cc

Deck Thickness 0.625 in
Exhaust Valve Diameter 1.810 in
Guide Plates Included No
Intake Runner Volume 210.0 cc
Material Aluminum
Push Rod Diameter 0.375 in
Valve Angle 15 deg
Valve Spring Diameter 1.550 in
Valve Spring Maximum Lift 0.600 in
Valve Stem Diameter 0.341 in

Edelbrock Performer 440 Intake Manifold

For rockers i chose : Harland Sharp

Manufacturer's Part Number: S70015K

Part Type: Rocker Arms

Product Line: Harland Sharp Heavy-Duty Roller Rockers

Summit Racing Part Number: CSP-S70015K

Rocker Arm Mounting Style: Shaft

Now i am looking at Carburetors and Distributors. With what i have so far what would you recommend for them? I have looked at the MSD Pro Billet , MSD Digital 6A and Blaster 2 coil.
I also have thought of using the Edelbrock Performer Series 750 CFM Carburetor with Electric Choke
SOOO with all that, i could use any good ideas on how to finish off my engine. Thank you.

Welcome here. Alot of folks recommend the holley street demon carb. On ign there are lots or pros/cons with MSD. Myself I like an OE 70's dist (& rework the curves & more) with an HEI module & an E coil. EDIT with further checking the RPM is a square bore & the Demon is a spreadbore but there is an adapter but another carb might be better, hang loose others will advize

Based on your cam and intake choice, I think the Edelbrock 650 AVS would be a perfect choice, more than enough cfm and it would make a snappy performer on the street. In my book, it is hard to go wrong with MSD. You did not mention what pistons/compression ratio you will be running and whether you will use headers or manifolds.

Actually i have no idea. He mentioned 9.5 or 10 to 1? i was going to use stock manifolds but may change my mind and go with headers. I am trying to kind of replicate my 70 SE i had in the 70s. It had side pipes and i was thinking going that route. I know i am stuck in the past lol,

There is a complete MSD setup for RB motors for sale in the engine section. Digital 6AL box, pro billet distributor and coil. Seemed like a deal. I'm a fan of their distributors as it's stupid easy to change the timing curve.

On your deal using the good heads and intake you have there is no way I would put a small CFM carb., less than 750 CFM on it to choke it down tsk
I have play with, built and race BB Mopars since the early 1970s, every BB that is a RB motors liked bigger carbs, 850 to six pack to a tunnel ram with dual 750 CFM and so on up
Your right foot controls how much air goes through the motor at anything less than wide open throttle , correct work
The carb. size controls how much air and fuel goes through the motor at wide open throttle work
Take a look at Quick fuel, Holley as well as the other carb makers out there scope Not just Edelbrock down
I and a lot others on here have had excellent results using the Holley 950 HP carbs. scope
Little carb, little power, big carb, big power grinshruggy

Cab is correct, your 440 needs at least an 850 carb. If you're going to run a 650, you better run two of them.

Welcome to Moparts, before you pick a cam, it would be best to decide on headers or manifolds, the cams would be way different between the two.

Stay away from the eddy 750 and 800. Buy a used 750-850 DP or HP carb, rebuild and roll.

that cam is better for headers, an xe 274 maybe even a little larger ground on a 112-114 lsa would be good for stock exh manifolds for your application, IMOP.

don't forget a decent converter for that, providing it is auto...

Man, I must have read another thread? From what the poster says, he is doing not much more than a stock 440 hp motor. He has a little cam, a dual plane Performer intake, not the rpm. He does not know his compression ratio yet, but if he had bought some 5-600 dollar pistons, he would probably know about it and what the comp ratio is supposed to be. He has good heads and rockers and was probably going to use manifolds and you guys really think he needs an 850 or 950 to feed maybe 400 horses? Sounds like a recipe for a slug to me, but, hey, I am just reading what HE says he already HAS and is going to use.

Well that sucks to know that's all I will end up with. I obviously have spent a bunch of money on not much. Haven't had a car like this since the early 80s . I am really wishing I went a different route now. The guy building my engine is very competent . I have read and read people s threads and have tried to make sense of it all. He said I would end up with around 430 to 450 hp and lots of torque. I really appreciate everyone's opinions. I should of joined this site long before I decided to go this way. I'll have like 7000 in this thing and it sounds like it's a boat anchor... Ugh.

Do you know what 400 HP feels like in a car that is traction limited work
If not you may be pleasantly surprised up grin

Exile, don't get upset, this is just the nature of forums and different opinions. What your actual compression is is critical to making these decisions . You have picked a cam and intake that will make for a high torque street engine. You have very good heads that would be even better with more cam, a Performer rpm intake, 1-7/8" headers and then an 850 carb might be warranted. You really have not stated your goals for this build which makes it hard to make recomendations. When I made the remark about a slug, the engine won't likely be, but with an 850 double pumper on such a mild combo I believe you would be seriously overcarbed which would lead to poor drivability, throttle response and fuel mileage if that counts. I stand by my carb recommendation as your build stands right now. Also, what converter and gear ratio are you planning on running as they all have to work together.

Thank you. I am just looking for a driver that has plenty of power if I want to punch it ,that it will get up and go. I am not looking to drag race it, not that I wouldn't like to make a CPL runs lol. I honestly had no idea that so much went into building a motor with components that would work best together. I haven't took my rear end apart so I have no idea what I have for gears. I do know that it is a 8 3/4 and limited slip? It was originally a 340 , Ralley package. I have a 2400 Stahl convertor that I was planning on using. I only thought of using stock exhaust manifold s as 73 never had a 440 so I wasn't sure headers would fit or work. Piston choice I was leaving up to the engine builder as I have know knowledge of what is best. I really am thankful for all the responses I have gotten. Thank you .
