On the air cleaner, air comes in from the bottom edge, the cover is a larger diameter than the base. Gotcha, just detailing some dissasembled cleaners at nicksgarage website and can note now you mention the base is just about the filter element diameter due the recession shape I seeing, and the top supports over the element not over the base, then get an extra room after the support area for it. No cast cranks till the 400. Pretty sure on 70 and 71 383 2 bbls got cast Non HP in 71 but forged in 70. Humm. I do have a 71 fury in the back with the 383-2 bbl. I'll that check out. Factory service manuals are pretty thorough.

"383 4 bbl 330 Standard camshaft standard valve springs, windage tray ( still debating ), high compression pistons, dual snorkel air cleaner, HP exhaust manifolds ( seems to be a standard agreement but still some doubts ), forged crank. No Magnum/supercommando denomination so, no HP stamp? Turquoise paint, I guess double timing chain ?"
I have a 69 Charger, H-code, 330 horse 383. Was 95% original when I got it. Engine is turquoise, not stamped as an HP motor. Factory HP manifolds, small round 340/383/440 HP air cleaner (no snorkels) with red 383 4-barrel pie tin . Standard 4v intake, and of course the car has A/C. I think the 69 manual states a specific carb...compared to HP stamped 383's (like 6 numbers listed). Did not have a double roller chain.
When I pulled the heads, they had red valve springs, and factory details that it had a standard 2v camshaft.
Essentially, it seems its a 2v- base motor with nothing more than a 4v intake, and HP exhaust manifolds. And all should have had AC.

I scanned through the posts in the thread and didn't notice anyone mentioning the fact that the 69 335hp 383 motor had positive deck height flat top pistons originally. If you mention that, somebody will insist that they weren't +dh, so I never say anything.

How much over DH got your pistons?
( yes somebody mentioned about that )
Did 2bbl engines get dished instead lower CH pistons? I thought they were simply lower ones.

I scanned through the posts in the thread and didn't notice anyone mentioning the fact that the 69 335hp 383 motor had positive deck height flat top pistons originally. It wasn't much but it kept anyone from just doing a quick bolt on of the 67 440 closed chamber heads to increase compression. You had to make sure your head gasket was thick enough to keep the piston from hitting the combustion chamber. When rebuilding the engines in the 70's, the catalog had a listing for both pistons, neutral and positive height. Consider this as a possibility as to why the horsepower rating was different. Eventually the taller pistons were just dropped from the books and like now only one is shown.
I recall this was one of the tips mentioned in the big yellow Direction Connection Racing Manual.
Perhaps Plymouth converted to the open chamber heads for emissions or some other Federal Mandate and the piston change was a little cheat to help performance. Me thinks your source got it wrong on the year of the positive deck height pistons on the 383 Magnum motor, I'll swear it was only the 1970 383 magnum motors that had the Holley carbs also that where listed by Chrysler to NHRA tech. department with + .005 deck height, just like the 390 HP 440 6 pack motors where

It was less than .100 , if my yellow book surfaces I will check to see if it mentions it. I've measured a few unaltered originals, they were all below the deck. The NHRA spec is like 0.020" proud, I have never seen one from the factory like that. I knew a guy that ran an A body 383 car in Super Stock had to actually grind on the pistons to clear the 906 heads where the head overhung the bore. The 1.932" CH piston was used in at least 1968 and 69 383, maybe 1970 too.

Here you go, fresh from the DC Racing Manual circa 1979. Let me clarify that I didn't doubt that you read that in a Mopar manual, what I should have said that I jhave never seen a production 383, from 1959 to 1971, that had the stock OEM piston tops above the decks You need to remember that the original beaded steel head gaskest where .022 thick and had a smaller bore size than the later 440/400 bore size .017 thick beaded steel head gaskets Which leads me to say do not believe every thing you see in print Have you heard the old adage to not believe any thing you hear and only half of what you see Many myths out there. Mopar, Chevy and Ford provided many false specs. to NHRA, NASCAR and other sanctioning racing organizations on many different parts they made for racing only that where not used on production cars

interesting reading from the DC book. I have the book but never advertised that... will search and read I scanned through the posts in the thread and didn't notice anyone mentioning the fact that the 69 335hp 383 motor had positive deck height flat top pistons originally. If you mention that, somebody will insist that they weren't +dh, so I never say anything. How much + have you measured them? Long ago, far far away. It was less than .100 , if my yellow book surfaces I will check to see if it mentions it. less than .100"??? still being .050 sounds a bit of too much for a factory assembly!!! I have had constanty bad decking jobs on my 400 and I'm worried now will have to cut it again and hoping will be getting around 0.020. on one of the sides. The other side seems to be at zero. Will use the felpro brass shim on that side to get both sides equalized. well that was a bit off topic.
