heavier valve springs, higher lift cam, windage tray. Heavy duty oil pump. Chrysler found the 330 hp engine ran right with the HP. Mine had a taller rear gear ratio, Actually the 335 HP designation was created to sell cars., so it was assigned to the RoadRunner/ Superbee line for advertising, period.(68-69)

I'm pretty sure the difference is when the 383 was installed in an "A" body car. They had an exhaust manifold that was very restrictive on the driver side to clear the steering.

This supposedly caused the engine to "lose" 5 HP

Otherwise to my knowledge a 383 with a 4 barrel was the same.

I am referring to the HP version.

The guys responsible for the 68' Roadrunner and Superbee wanted something special to advertise, so "440 cam and Heads" and 335HP was the ticket. They also got the 440 R/T automatic transmission, and stamped HP on the blocks,like the 440 R/T. (68-69)
The 330 HP had the same compression ratio, Intake, and Exhaust manifolds. But the carbs were different.They had a milder Cam, and no windage tray. My 69' also came with 2:76 gears. According to the Chrysler engine testing group, they were astonished that even with the upgrades, there was only a 5 horse Improvement. But the ad sure sold a lot of cars. I have the 330HP in my car, and it runs every bit as good as the 335HP version in my other car. With the type of gas we have today, I'm not so sure putting 9.2:1 pistons in a rebuild wouldn't be a better Idea. For an everyday driver.

The 67-69 A body 383 engines got a variety HP results due to that restricted driver side manifold, so I take all those ratings with a grain of salt. A 383 A body is certainly more rare, but for regular use I would take the 340 "Baby hemi" over it any day. if for no other reason the handling was superior. Driving a 340 to me is like riding a 73' 900 Z1A Kawasaki back in the day. Very mild at an idle, but rev it up, and your gone!LoL

The only difference is the camshaft

The only difference is the camshaft

and valve springs, windage tray and different carb.

Nice reference. Ever ridden a H2 750 two stroke? YIKES!

Texas 69 bee posted a great link to the same discussion that was on here earlier.

I read it and learned some stuff.

It's a great link. Thanks for posting it.

Oh yea,
I almost bought a 750 H2 in 1976. It was in the driveway next to the house I rented. beautiful bike with a for sale sign.
I knocked on the door, and my wife,standing next to me, saw the door opened by a guy in a wheel chair. I asked;whose bike, and how much? he said: it was mine,,,, my wife looked at me with that telltale frown, and said sorry, we were just saying hello.I took that to mean exactly what she meant. They were a very squirrely bike, but very fast.LoL

and valve springs, windage tray and different carb.

Nah, 69 330 horse c body motor HP manifolds, dual snorkel big base air cleaner, carter avs 35k miles was sitting on a crate when I bought it. Pulled it apart had windage tray.

I sold the manifolds and the motor on c body dry doc and the air cleaner on ebag

I could maybe believe the valve springs but the hp cam in NON AC cars had a tiny bit more duration no more lift if I recall dont think it was enough to call for more seat pressure or open pressure even maybe 5 degrees .

My point is the 330 horse motor is just as stout.

 

[monaco66coupe]

They are just as stout. But the carbs were non high performance, and if there was a windage tray, somebody put it there.The 1968 factory parts book shows no application for it on the383 Chrysler or Dodge, except superbee
The lift is lower as well. The 68' Charger 383 four Barrel used a 425-.435 cam, same as two barrel. The Superbee used the .450-458.Both 330 and 335 used the same carb in 68' only. In 69', 4615/4616S was the 330HP, and the 335 HP was 4711s/4682S. Air cleaners were the same regardless,as were Exhaust manifolds. I agree the 330hp is every bit as good, I like mine very well.

 

[dieseldazzle]

Im talkin about 69 motors and I can tell you it was an avs and had date coded 69 spark plug wires on it. I bought it from Bill k out of hollister.

Non A/C motor. I put pics and posted under my old screen name on here.

I changed it because I lost the password and dont use the email account anymore it was court9155

 

[monaco66coupe]

I am as well,as in 69' there were four Chrysler carbs for the four barrel 383. two for the 330 and two for the 335. The cam application 330 vs 335 was the same 68-70. The 69's got more complicated, as Holleys entered the picture. The oil baffle was a 383/335HP and 440/375HP feature in 68-69'. Now, in 1970 Chrysler used the same cam in both the 330 and 335HP, as well as oil baffle. it is possible your Chrysler was a late year car, and it got it. Nothing was that tight date wise back then.
I can say driving both I can't tell any difference up to 100MPH, and I have no Intention of going 130MPH to find out for sure. I'm OLD!
I use this book all the time, and the Data matches the Blue factory parts book.
