Hi I'm Felix from Germany
I want to swap in my old 383 but first we want to rebuild them
We have a set of new Pistons 0030
Original 383
So we think about follow parts
Edelbrock 650 cfm
Edelbrock Performer air intake
Edelbrock Plus Camshaft
Original Crankshaft
Original Rods
Original 906 heads with valve springs from edelbrock
Transmission TCI 727
Torque Converter I don't know
Rear axle 8 3/4 with 3:23 sure grip
Can help anybody me .
Thanks Felix

Welcome aboard Felix. sounding like a mild daily driver? TCI rebuild kit I am assuming. I would suggest some Stealth aluminum heads as opposed to sinking money into antiquated 906 iron heads. more details: what vehicle, what application, budget. do you already have the 383? better would be a 400 block with an offset ground 440 crank for 470 cubes & the external dimentions would be the same for fitment

Did you notice he is in GERMANY ???

I agree on not sinking money into those heads , but it may not be an option.

I have a 69 HP engine
With 0030 pistons and a original crankshaft .
I want to rebuild the 906 heads because i have not so many money this year.
Which parts are the best ?

What part number pistons do you have ?

Everything you have listed is fine to use, do you already have the TCI transmission , if it's just a streetfighter it's nothing special. A basic rebuild with stock type parts and a shift kit, you pay the big bucks because you are paying for their race sponserships.

You really need to look at the pistons and heads to make sure you have enough compression. Some 383 pistons will give you extremely low compression especially on a 906 head.

Don't ask me how I know........

I bought this set in summit Federal Mogul Premium Engine Rebuild Kits MKP-667E300 here is the part number
I don't have any transmission for it .
You can watch on summit thank you for your help

Agreed. You can overcome some of this with a cam that has a more aggressive lift rate. I think there are better options out there than that Performer RPM cam if you're using some ~8:1 Speed Pro flat tops.

The Comp XE268 will work with power brakes and a stock converter. It will also preserve some of the low end you'll be giving up with the loss in compression.

You don't want that kit , if you have not bought it yet don't, it uses this piston which will give you barely 8.0 compression .

383 piston selection is horrible, the stock piston in the 69 383HP is .0025 in the hole , with the stock 906 the compression is barely 9.2 , not the 10.0 that chrysler rates it at.

The TCI transmission is grossly overpriced for what you are getting, don't waste you money on it either. Contact John Cope/CRT and see what he can do for you .

The OP mentions money being a determining factor in the short term. That engine kit will get the car on the road inexpensively even if it isn't an ideal piston. Based on the parts list, I'm inferring a slightly warmer street engine is the goal. That can definitely be accomplished with smog pistons assuming the OP picks a cam that makes the most of cylinder pressure--and octane rating will be a complete non-issue.

Money is the funny part , here is the same Kit with Forged piston , though it is with a .040 over piston. it's cheaper than the cast piston low compression kit.

And a kit .030 piston and oversize bearings , I don't know if he has confirmed the crank is ok at std journal sizes?

No way is a Comp XE268 the right cam for an 8:1 383. The largest cam I'd say fit the bill would be Nughes SEH1016BL-12 http://www.hughesengines.com/Index/produ...mp;partid=30251
Or Lunati Voodoo cam 10230700
Or Comp XE256H 21-221-4

Another thing is compression: Don't put a lot into the 906s right now, the Edelbrock E-Street heads at 75cc will put the engine right at 9.0:1.

What is thing I can do with the Pistons then I bought .
Edelbrock plus camshaft ?
Original transmission ?
Torque converter stock ?
Edelbrock 75cc heads ?

Car is a 71 super bee Charger
Budget with Engine Transmission rear axle 6000-8000€
I have a 383 from 69 HP
Piston Rebuid Set from summit

You already have the kit so it's not as easy as just sending it back , I imagine it wasn't cheap to get it to you .

Is that budget entirely for the engine build? Because that works out to a max of about $9000 US.

Which is a lot of money for a 383 rebuild.

I don't know what pr9cves are like in Europe but that would be a monster build here. A complete 440source stroker kit is $2249, rods, pistons, crank, bearings all balanced and ready to install,.

Another $1000 gets you a pair of all new aluminum cylinder heads.

That's less than half your budget and most of the hard parts done and new.

Hi Felix,
I'm with JohnRR on the pistons, the selection is horrible for a 383.
Maybe you want to join the german mopar-forum.de - a lot of knowledge and easier communication.

How good is the gas in Germany? 906 heads are fine, tons of race engines used these heads and did fine. Don't go over board on the cam, takes away drivability. Most here on Moparts will have you building a $50,000 race engine to putt around on the street. Keep it simple, you'll be fine with what you got. Good luck on your endeavor. Let us know how it works out. Mike

Felix,
Please tell us what items you have already purchased. We can work from there.

You do have to watch out for racers telling you how to build a street engine. It happens all the time here.

When you respond we can get down to the most bang for your Euro. Doesn't sound nearly as cool as "bang for your buck", where the word buck is slang for dollar. (And the word dollar is derived from your word thaler).

R.

Yes 906 heads are fine, but not with a piston that is speced to be used with a 516 sized/shape combustion chamber.

Tons of race engines USED them because they were all they had to use, or the class specified them, otherwise they are a POOR choice, especially in a 383 that is hard to build compression in to begin with.

I just did the math, 90cc head, .041 gasket that is in the kit he bought, a piston .087 in the hole on a blueprint block (1.848 ch), his block may be a little taller, 7.52 compression ...

He's got a 383 not a multi dollar blown Hemi. What he's got will make a good street engine for the money he's ALREADY spent. What ever we spend for the good heads here in the states, double that for him over there.

I'm not saying he needs to spend millons on a head, it is what it is.

Are you ASSuMEing he has a super duper PORTED head off someones race engine? In stock form a 383, in a car weighing almost 4000 lbs, overcammed is going to be less than impressive, especially with 7.5 compression...

Hopefully joining that group SuperRob mentions will garner him some help , hopefully parts wise and finding a capable shop that can build that engine right.

I have a 383 Engine oversize 0030
Original Crankshaft Original Rods
with the Rebuild Set from Summit
Federal Mogul Premium Engine Rebuild Kits MKP-667E300
And a 8 3/4 Axle
I don´t have a transmission or camshaft , air intake
i want to use the original heads 906 because i like the original .
i dont want a race engine
i want a little more than the original engine was.

For a street 383 in a fairly heavy car, been there & done that, and here's what I'm thinking given what Felix has told us so far:
You can either return the piston kit and get one with more compression from the same source, or look at 440source.com and see what they have. A cast piston will be fine but forged holds up better to detonation.
Not knowing the octane ratings in the Fatherland, I wouldn't want to go more than 9.0:1 on an iron-head Wedge @ 91-92 octane.
The Edelbrock cam is kinda short on lift, but IF you also need rocker arms, a 1.6 ratio would help that. Otherwise, look at more modern stuff like the various Comp Cams, Engle choices. Something in the 214-224 @ .050 and around .450-.480 lift will be mild enough for a stock converter at 9.0:1 CR. I've used as much as .504 lift at that duration with tall gears & stock converter and had very nice street manners.
With old stock heads & block, a surface cut is likely needed for flat decks on both. Good machine work, balancing, and a good valve job go a long way; find a GOOD machine shop that's familiar with American engines and has an eye for details. There's maybe .5 CR there without going nuts.
I like double springs on the valvetrain, and at least a windage tray. Use a dual-plane intake (look in the ads here for nice used), and a 650CFM carb would be adequate.
The Eddy & Stealth heads I've used all needed a better valve job, and the springs & parts were OK.

Gas stations max out at 95 octane (called ultimate102 over here).

If he could find even a set of 516 heads over there those with a little porting and 1.74 valves that would be better than the 906's , but he would need to get a piston that is closer to zero.

DO NOT HACK .087 off the deck to get those pistons at zero , it would be cheaper to just buy another set of pistons from summit and have them shipped over. Which wouldn't be a bad idea,in the long run that will save him money.

I would go with a dual plane intake & a fairly small carb possibly one of the newer ones that all the metering systems are adjustable. Holler what parts you go with & how it turns out (if it meets your expectations)

I just went through this on my 67 383. I bought KB pistons and on paper I was to be at 9.0:1 compression. Measured came in at 8.2:1 and I cried.

I fortunately was able to recover by milling the 915 heads 0.040 inches and that got me to around 8.9:1 (from what I recall - could be a tad less). But that was with a closed chamber head - the open 906 head puts you in a much worse position.

What does it really matter if it's 8 to 1 or 10 to 1 on a STREET engine. It's a done deal for him, get the cam and induction right and he'll be fine. I dought he has the three figure income like you guys on here that can just buy all those high dollar parts, he's making do with what he has. Help him out and quit telling him he has junk (which he doesn't).

a 3-figure income would be max $999 a year...

As opposed to the regular compression-wasting thick 0.039" FelPro headgaskets, one can use steel 0.020" headgaskets to increase the CR a bit.

Also, before you go ordering a 'new' transmission, there used to be a time when 'TCI' was better known for Total Crap Inside...

IMO, a normal/stock 727 will be beafy enough for your use.

a 3-figure income would be max $999 a year...

What was I thinking? I guess what I make. LOL

If you haven't rebuilt your heads yet, you might consider the Edelbrock E-Street heads. The 75cc e-streets, part # 5090, are around $1300, available trough Summit, and would bring compression up to 8.5:1.
