Information on 383/440 mopar intake 68-69 engine

[firstgencharger]

I have been researching an intake for my 1969 383 engine and have read about an intake that was used on the 1968 440 block. It was a high-rise 4-barrel intake manifold with the 440 high performance camshaft, available for the Road Runner and the Super Bee.

Question is, what is the casting number of said mentioned parts?

Is this correct, and is there an option (current or otherwise) for using this setup?

I have not found any info for this combination in my research and am hoping you racers may be able to shed some light on this. I am pondering using this combo on my 1969 block which is not an hp.

1st the RB-440 high deck intake, will not fit on a B-383 low deck engine combo, the RB-440 wedge {also the RB-413, 426w, even very early RB-383} is a taller & wider block, than the 350-361-383-400 B-series Low deck wedge engines are... not sure what factory 4bbl high rise your even talking about either, in 1968 or even 69 except 440-6bbl Plymouth/440 Six Pack Dodge, {RB-440's} were all basically cast iron/low rise on the single 4bbl manifolds, with a spread bore pattern for the Thermoquad carburetors {smaller primary & larger secondary holes} or square bore {4 holes, same sizes} for the AFB or AVS Carters, a few square bore Holley's too... if your doing a 383 maybe a original 335hp/383ci Road Runner Engine's, intake manifold... sorry I don't have the casting #'s in front of me, if your building a performance engine there are far better aluminum 4bbl intakes, for either the 440 or the 383 available {what ever it is, that your building} in the aftermarket, than the cast iron originals, that will/should fit under the stock hood....

back in '69 plymouth did an aftermarket package thing and advertised it in some of the car mags. it was a '69 roadrunner with an edelbrock dp4b intake, 3310 holley, hooker headers, and the old "street hemi profile" cam and 3.91 rear. plymouth had ronnie sox drive the car at the strip for advertising. if you can find any old 1969 car mags you may be able to find the add. no 440 intake will bolt to a 383; unless your using stage 6 heads.

Yup, there are better aftermarket intakes but, the hi-po 383 came with a decent intake from the factory if that's what you're asking but don't remember the casting number. I think the last 4 numbers were 6301....but iirc, it also came on stock type passenger car engines.

There are subtle differences between the 68 and 69 intakes for 383 and 440 but nothing that would prevent one year from running better than the other. The difference is in the choke stove area and the 68 has 4 holes while the 69 and up had two racetrack shaped holes (connecting the primary to the secondary but still divided plenum). That's the beauty of MoPar. Any big block part from 1967-1970 is good, or at the very least you can make do on a hot street car.

firstgencharger, as everyone has mentioned, getting the original 383 hp intake is pretty good for street use. I don't know what sources you were reading, but in 1968 the 440 engine wasn't even an option on the road runner. However, the 335 hp. 383 did use the same cam as the 440.

I want to thank you all for your input.

I was questioning the statements made by author Don Taylor in his HP Book published in 1994. In this book, he states that "In 1968 the 383 was equipped with 440 heads, a high-rise 4-barrel intake manifold and the 440 high performance camshaft", which he states "were available in both the Road Runner and Super Bee".

He further states that " the 440 heads from 1967 proved to be real champs and were used to give one last hurrahfor the 383".

I am on a shoe-string budget (who isn't) and am looking to use mostly original parts (hopefully cheaper) than new expensive items.

I have purchased the intake #2806301 which is for the 1968/69 383 engine, but was not sure if this was the intake he spoke of as no part/casting numbers were given.

I respect your collective experience and do appreciate any more information pertinent to this subject!

Than you all!!!

Well, in 68, the '906' head was introduced on the high performance 440 and was used on the road runner 383 engine too. The 915 large exhaust valve head was used on the 440 GTX and RT for 1967 but the small exhaust version was used on the low performance engines, 383 (and 440 iirc) in 67 (66 too?). Mom just decided to say the 383 high performance engine came with the 440 head. It would have came with the 906 head no matter since the 915 head was discontinued but the 383 high performance engine did use the 440 cam. The high performance engines also used a flat damper spring on their heads but I had a 330 horse 383 with the same heads and spring setup but it sure didn't run like the 335 horse engine either. Did the cam make that big of a difference? Mine was in a 70 Challenger non RT but had dual exhaust (factory turn downs), AVS carb, disc brakes etc. It ran good but not like the road runner or any of the other 335 horse cars...

1stgencharger, unless you are doing a restoration or racing a class that requires original parts, I have found used high performance parts to be cheaper. Swap meets, Craiglist, racer hand-me-downs have saved me a ton of money. For example, you can pick up a Performer intake used for less than a $100 on average because most want a RPM now. It will be better than any cast iron one.

I just love it when someone says that his 383 has 440 heads. 383 and 440 used the same head for all years except the 67 440 HP 917 head. Same with the 400 and 440, same head. 69 383 2-bbl had 906 heads.

Well those people are probably just repeating what Chrysler said. Plymouth's 1968 road runner ads mentioned that their 383 had 440 heads. It is true after all, even if there was no other choice.

Yes the best stock intake manifold for the 383 is the #301,I run it on my stocker car runs low 12's stock afb 3611 carb

I am enjoying the continuation of this thread, and I appreciate all the information that you mopar racers have been giving me.

As a rather newbie to this site, I am soaking up info from books, magazines, forums and the like, as I have been deciding how to build my 383 for the past year or so.

Don't think I will be able to afford the machining of the block and heads though. Any thoughts or suggestions? I'm looking at a mild build with less expensive parts.

What is it that you are you doing exactly with the 383 ??, what are your expectations or future plans ??, how mild or how wild ??, street/strip or just cruiser ??, what kind of budget ?? Do a specific & detailed out-line for your build, spend wisely, this stuff isn't cheap, do your research, also I suggest that you save your money & buy quality parts, not just the 1st thing that comes along, even if it takes longer, you will be much happier in the long run, especially, if you don't have to do stuff more that 1 time, what's your knowledge base ?? do you know the basics ??, what kind of tools do you have ??, did you get any books or a Factory Service manual ??, are you mechanically inclined ??, can you understand the performance talk/lingo ??... Mopar Performance Engine 9th edition #P5249704 is a decent book, with a few combos, that are tried & true, for the budget minded... There are allot of books that are available, a few shown below, get to know what it is your looking at & know what people are talking about 1st, look at my signature line, it reads "Fill your Library, Before you fill your Garage" & I completely stand by that Mike Joy quote... Knowledge is the key... One thing to remember, an engine is just a big air pump, what goes in must come out, so if you improve the intake side, you should improve the exhaust side equally too, cause & effect, the more you understand how that works the better... Cylinder-head work like porting larger valves & proper length & style pushrods, lifters, rockers, valve springs, retainers, locks, seals to match your specific build & camshaft etc. is money very well spent... After all the camshaft, intake carb, ignition system & exhaust are very important part of the overall combo, they need to be sourced & matched for the type of intended usage.... It's more than just the engine, the suspension, cars weight, wheels & tires, brakes transmission & gears, are all equally as important, for any performance combo... good luck & happy Moparing

I have most of the books listed above(edelbrock not holley), and believe in the creed of "Fill your library before you fill your garage".

What I am interested in is, what has worked for you racers as far as parts you have used to build a mildly performing street machine?

I have the update on front disc brakes using the A-body spindles and later OEM parts (B,R, and FMJ cars) to replace my front drums (I am short on funds) but do have the 11" rotors which I will replace, and the slide type calipers; the original intake which was missing (2806301), and the original water pump.

I have pulled the heads off and have a noticeable ridge, aside from using a ridge reamer, do I need to have the machining done to the block to clean up the cylinders, or can I just clean the ridge up and give it a hone job as it will be just a street machine with some attitude?

A new cam and lifters could be my nest purchase. I intend to tear the motor down when we get back into the warmer weather. I have read a lot of books over and over and find little nuances that I have missed previously, have looked at many sites, and am still researching what is possible for the Charger.

Thanx in advance!!!
