I think it is the 4Bbl engines that may have the + pistons, mine is a 69 and flat top pistons, would be cool to see yours.
My engine has never been out of the car so the deck has not been milled.

If I remember correctly the ads or road tests of the new RR and Super Bee stated that they came with 440 heads. Maybe that lead to a a lot of confusion. I have old mags from the era and I am curious about what they said.

I was looking at my old Mopar Performance Parts Big Block B/RB engine book P/N P4876825
And in there it states that the 1968 and 1969 383 engines(4Bbl) have positive deck height.

I know that just because its in the book, does not make it true, but just thought I would throw that out there.
They were also saying with stock pistons(with NO valve pockets) that you should stay away from camshaft duration larger then 285 degrees, and high lift cams, they do not go on to give a number of what you are safe to use.

Think about this, if the piston is above the deck and the stock beaded steel head gaskets where(and are) .022 thick what is going to happen
The standard acceptable minimum safe piston the head clearance is .035
No worky very long my friend, your buying misinformation as truth
When things don't make sense, their is usually a reason for that

On this episode of mopar-myth-busters, we'll check the piston height on a stock, H-Code, 1969 Charger SE with the mischievous and mysterious 383-330 horse engine, with original pistons.

And the results on this one: APX .005 to .008 ABOVE deck.

Thank you.

I do not know what all 68/69 engines are, but my 1969 H code 383 4Bbl a/c engine(330HP) has pistons that are above the deck surface, That is a fact, I just changed heads, Now I wish I had measured how much above the deck.
So as far as buying miss info as truth, the Chrysler guys had a hand to do with that because they built my engine with Positive deck height AND they printed info about it in books.

I can only speak for my engine, but there are a ton of cases of people having the valve kiss the top of the piston using camshafts, that are not all that crazy, by most engine standards, I was just trying to help some one avoid a costly mistake, as I will limit my cam choices to the Magnum/Roadrunner cam .(I also used the steel shim Mopar head gasket, and at Mancini's price I got three sets,its nice to have stuff on hand,just in case)

I did post the one photo where you can see the piston sticking above the block.

But I am gonna guess most 383 engines are not using the stock factory pistons anymore like my engine, so it may not even be an issue to most guys. As most new pistons have valve pockets in them as to make valve to piston clearance exceptable.

If using 67 heads then yes would be close, but the 68 up have an "open" chamber, made for the 440 bore
On a similar note, I have a 383 with the TRW popups with zero deck and 67 heads, blue felpro gasket. That engine had some get up and go.

THANK YOU CDP!!!!!!!!!!!!!!!
I been trying to post photos and I suck at computers.
I am not a guy who tries to post wrong info, If I do not know then I post that, and I JUST had my heads off, I am just trying to help people. THANKS SO MUCH

The piston has a taper to the top, so the edge sits in the cylinder, but the top of the flat piston sits above the deck., Sorry my photo sucks, as at the time I was not trying to prove deck height.

No problem.

I put the shorblock together some time ago and its been in the corner of the garage for a few years now, as other projects have taken over. I never really paid attention to the deck-height, but after reading this forum, it got me thinking and I had just a couple bolts holding the heads on. So I did a quick check with my trusty calipers. Due to the chamfer, that you mentioned, its tough to measure, but I came up with .006, but I think its slightly more. I don't have an indicator handy at at the moment.

To reiterate this particular H-code 383/330 horse engine out of our 69 Charger: It is an AC car, with a turquoise, non-HP block. It had red springs on the original heads, and a standard, I think 666 intake manifold, along with HP exhaust manifolds. The carb was replaced with an AVS, so I'm not 100% sure on what carb it came with originally, but it appears it may have been a holley 4160 series. No windage tray, but 402 pan. I tossed the original came, in favor of a full Lunati matching kit, but what I had researched a few years ago, and several threads on here, is that they had a 2v-camshaft. The pie tin is red, with the "383-four barrel" designation, with the standard small round HP-air cleaner. Some where, I have pics, but they are from a long time ago, and the cars been long time torn apart.

My car sounds just like yours, except mine had the duel snorkel air filter, but my car had the "N97" Noise reduction package, and that got duel snorkel air cleaner housing.
I think California cars got the "N97"
I guy just showed me how to find that out on the build sheet, it is not on fender tag.
So that my help clear up air cleaner housing differences between the engines, one was built with the standard air cleaner and cars with the "N97" got duel snorkel.

I also think mine has the "301" intake manifold. But the rest is the same. I have not had the oil pan off yet to tell if it has a windage try, I would guess that it does not have that.

301 intake would be the correct one. I had one of each and couldn't remember which one belonged where.

Your N97 sounds right also. Would love to see more pics of the car your working on.

Another correction, I was wrong on the valve springs. Found the original springs(replaced with lunati) and they were std. 2v springs with no damper, which was stated earlier from the factory service manual.

If I remember correctly the "noise reduction package" also had regular turn down tail pipes, no chrome tips

That is how my pipes are, I had thought that maybe the tips were removed or didn't have them.
So did all cars, with out the N97 package all have tips on them?

Can't say for sure, there might be exceptions, but tips, mufflers and air cleaner are a package deal. Either or, poor Californians at the time had to put up with that crap, now most "people" there should have that package, lol.

Turn downs on ours also, no tips. St. Louis built charger.

I never remember seeing chrome tips on b-bodies unless it was an R/T, Super B, RR or GTX. In 68 I think it had to be. Hemi to get the tips on RR and Super B.

Better late than never

4-8 up one bank 2-3 the other with piston tilted
68 2bbl 383
9cc dish piston

I remember reading that in a 68 Roadrunner add. And the reason being up to 1968 the 383 and 440 had different heads. After that as far as I remember both the 383 and 440 used the same 906 head up to 1970. But before 1968 the 383 used the small 1.60 exh valve heads and the 440 the 1.74 exh valve heads.

I believe in 1967 the 383 in the A-body (Dart & Cuda) that was rated at 290 hp used the small valve 1.60 heads and the 383 two brl cam. I think in 1968 the A-body 383 got the large valve 906 heads and the 300 hp rating and in 1969 the 383 A-body got the better 383 Roadrunner/SuperBee cam and the 330 hp rating. All in all it sure can get confusing. Ron
