Not sure if this the right forum for this, but interested in getting some more info on the 67 SS cars. Read some various stuff on the internet, but not sure what is true or false so here it goes. Hopefully some owners of these cars can chime in:

How were the Hemi engines marked, standard Street hemi data on the pad, or did these motors have a special stamp.

Same on the inline Vanke modified intake. Is there a way to identify them as original production versus over counter or some one else modified?

What carbs came originally, was it the carter cheaters, or modified stock 67 carbs. If the later, how were they identified as modified? Any additional tag, stamp, or serial number?

Lastly, the Mopar parts manual and service manual implies the CA CAP hemi cars got the 4324/4325 carbs either transmission. But there also was a 4402 rear Auto. The Carter data book say the 4324/5 carb were for Manual transmission and the 4402 rear was Auto. What is correct?

So for a California CAP hemi in 67 what carbs did come with the 4 speed versus auto. If the 4325 was either, why was there also a 4402 for the auto? The 4402 is not listed in the service manual I saw.

I remember hearing that the 1967 SS RO hemi cars came with 750 carter crabs on them, not the same as the smaller Street Hemi carbs had , at one of the old Mopar drag race seminars prior to 1980 before they went B.K. the first time IHTHs

George,I have a revised Carter sheet that list the 4402 as 67 rear auto with C.A.P.

I had two of the original blocks for those 67 SS cars and did not know it until I traded one of them off. One of them I bought as a complete engine. The engine was purchased by a son of a Chrysler-Plymouth dealer in Coleman,Texas. He took a brand new 67 GTX off the showroom floor and ran in on the street for a total of 1200 miles. He then pulled the 440 and bought a complete 67 SS hemi. I’m not sure if he bought the motor over the counter or from another racer but it was a complete motor. There where not many race Hemi parts floating around in early 67. I saw the car at the dragstrip in Abilene in the early 70’s. He ran it in SS. I bought the car in the 86, installed a 440 and sold it. It had a rat roaster with a single four that the last guy had been racing. He gave me the original Vanke modified intake, but had sold the carbs off to a guy in San Angelo, Texas. It had the original dated heads as well. The block was stamped differently than most of my hemi motors I had at the time. I had another block stamped just like it so I did not think anything about it. I’m not quite certain where I got the other block. I traded it off long ago. If my memory serves me correctly, it was stamped HC 426 MP. Most hemi blocks were stamped CH 426. I was reading an article in a magazine on day about hemi stampings written by Rick Ehrenburg. He listed all the stamping on the pads. He claimed that a 67 SS hemi was stamped with the MP ( maximum performance) just like a max wedge.
Now, do I know for sure it came out of one of the 110 SS cars from 67? No. It could be an over the counter complete engine. The dealers son had plenty of money and hung around with all the big name racers from this area. Phil Nichols, Shay Nichols, Shelby Jester, Gene Snow and a few others I can’t recall at the moment. We had a good strip at the time called Steamboat Mountain Drag Strip.
I’ll tell you who I sold this second block to, though. Joel Nystrum, or HemiJoel on this board. He has a 67 SS car. I seam to remember him telling me after I sold the block to him that he had verified this through his addition research. I think he said most all of the blocks were cast on one day. I’m thinking it was 10/31/66. I thought it odd because I had two blocks cast on Halloween!
I have not though of this in a long time. You might give HemiJoel a shout. He still hangs out here.
I still have that same Vanke intake.

Thanks for the info. Bill yes the Carter data calls out the CA CAP 4324/25 as the Standard trans. The 4402 as the Auto. But does not spell out what front carb for auto. So was it the 4324 or did they still use the 4139 like they did for normal 67 car.

Also, The Mopar parts manual and Service manual for 67 says the 4324/5 was for both transmissions. Conflicts with carter. And only the parts book mentions the 4402. So why two rear carbs unless the 4325 was really 4 speed only.

The reason my interest is I picked up a pair of the these Cap carbs 4324/5 complete with manifold, linkage fuel lines etc... When I remove the carbs from the manifold, which was the late 66 or 67 style. It had the vanke mod. I have not opened up the carbs yet, Just prepped them breaking free all the screws and such.

Just made me wonder reading up on the 67 SS cars. They apparently were dogs compared to the 64/5 cars. Stock street compression, with the inline modified intake, and the modified carters. I was told that NHRA disallowed those cheater carbs which are listed in the Carter data form Nov66. So what happen, were they disallowed after delivery forcing Chrysler to send new 67 carbs? Or did they get disapproved before delivery giving Chrysler time to swap them.

How would these modified 67 carter carbs be distinguished from the stock versions. Carter seemed to have part number change any time a part was modified, and in the case of carbs even a jet change.

The other really interesting thing about these carbs is they have an additional part number stamp on the rear of the carb flange with a 2 digit serial number. That 2 digit number is also stamped on the air horn top along the rear flange. Never seen a carb like that before. Could that be how they documented these SS carbs? If so surprised 67CAP carb would be modified. Or was this some sort of emission requirement and Carter or Mopar serialized the carbs in 67.

The street hemi carbs have smaller primary throttle blades than the secondary do, the 1967 RO SS carb had the same size throttle plates front and rear

Only ONE smiley on a C B post ? ... Tom must be rationing them to C B in this new decade !

It’s my understanding that externally the cheater carbs looked the same as the stockers. Correct?

You should be able to find complete engine and carburetor specs at NHRARacer.com

Another source of information would be ClassRacer.com.

I have a friend who raced at 67 they had purchased from Don Grotheer. They eventually switched it from a four speed to an automatic and I don't remember having to change carbs. They raced it at NHRA National Events so I think they would have been bounced if there was a problem in tech. They actually set a National Record on speed but I don't remember if that was with the four speed or automatic.

George,Have a friend that has an original auto WO car,carbs are 4345 front,4346 rear. The car has sat and hasn't ran since back in the late 70's but 100% original.

All the early AFB except the 3705 had the same small airhorn for the small air cleaners, I've never seen a set of the 1967 SS carbs so I'm not sure about them and if they look like identical to the street hemi carbs or not

Bill, Thanks. That would imply they came with cars if they have the 66 date code. The carter Sep66 form shows those. They are the 1 11/16" pri which required a modified inline manifold. Supposedly these cars came with the stock air clean installed, with modified base in the trunk to run with no air cleaner at the track.

I did look at the NHRA data for 67 and those drag strip pkg carbs were not listed. Typical 66 and 67 carbs numbers from the street cars. So that would indicate as I heard, NHRA did not allow them. According to the Chrysler letter on these cars, they were street legal, but not really meant for it because of the mods. Noisier, higher oil and gas consumption, high idle 1500rpm, etc...

Back to the 67 street carb question. I wonder if the 4402 was a late change for the Autos. The only difference between a 4325 and 4402 is the choke piston. May have been a mod to get emissions inspec for cold car at idle. Later in 68-70 Mopar did use different choke piston between 4 spd and auto for the hemi carbs.

pretty sure the cheater carbs were not allowed by nhra. pretty sure they were an over the counter thing.

67 used a 3705 type main body, small air horn and street hemi throttle shafts. Vanke intakes are not marked as such, look all original on outside.

Hence the dilemma with conflicting info , and trying to get ground truth from 53 years ago. The Chrysler letter documenting the introduction of these cars stated they would have standard size street hemi carbs modified for better fuel distribution. This is a Feb67 letter. The Chrysler race manual does not talk about the 67 RO/WO cars at all.

Carter show the "Drag Strip" package carbs (limited production) 4345/56 on a Sep66 Form as part of the normal Chrysler 67 carb data. So they must have been planned for these cars. Also they were over the counter in later years as I have seen 70 date code carbs.

If NHRA disallowed them, how did owners get legal carbs modified to work with a Vanke modified manifold?

One thing I did see in race manual for inline using the rat roaster manifold was removing distribution tabs on the street hemi carb besides jet and rod changes.

Which get back to the carb set I have that supposedly came from a 67 Belvedere Race car. 66-67 Manifold modified like Vanke. Carbs that are modified with distribution tabs removed, larger .107 and .104 jets and staggered rod. They have stamped serial numbers also which seems odd to me. So are these just modified parts a racer did, or could these be Chrysler modified for the 67 SS cars???

There was a jetting kit released by Chrysler for use on the “Vanke” manifold which included boosters, rods, jets. I beleive the cars came with this kit already installed. If the boosters are stamped with the part number then likely they are the same as in the over the counter kit,

The cheater carbs are called exactly that because they looked stock on the outside but had larger primaries.
You would never make it through NHRA tech with those carbs since tech measure the main and booster sizes amongst other things in the carb. Every time we went through tech they always checked the carbs.

NHRA does not list them as being legal because they have larger primaries than stock.

Back in those days the factories needed to make 50 cars, in each brand, with special race only packages, to be legal for NASCAR and NHRA hence the 1968 Hemi A bodies and the COPO 427 Camaro in 1968 and the M code 1969 A body 440 engine cars and the 427 Fairlanes and Comets NHRA has never been very friendly with Mopar or Mopar racers
I remember being told that the M code 440 cars A bodies weren't allow to race in "Stock" in 1973 and maybe up to 1980 because they where a SS only package according to NHRA tech at that time
Things change in NHRA politics hence the 427 Ford 410 HP 427 Fairlanes being allowed to race is A/S in 1974

I under stand the carbs were not hemi "street" stock, but what I don't understand is what qualified as "Super" stock acceptable since they may have come on them in 67 as Cab Burge stated. Max Wedge cars had these same big primaries.

New knowledge for me about the kit with venturi too. My front carb venturi's match up stock to the street 67 carbs by part number. The Rear carb primaries are different numbers, and all 4 seem modified. Not only tabs removed, but discharge port on secondary plugged, primaries have pickup tube emulsion holes soldered closed. 3 open vice the normal 11. I need to measure the bleeds and jets to see what they are. Thanks for the info.

Was there any sort of tech letter from Chrysler on this? Or how to instructions. The race manual I have doesn't talk to 67 cars.

The jetting kit P2836137 came with part numbers and instructions on the booster, rod and jet placement.
This is for the Vanke manifold.

The few kits I have don’t have soldered tubes, none have sniveys.

Could you send me a pdF copy of the instruction sheet of post it. Would be very helpful. Thanks for the info.
