can anybody please help me with a carby number for a ht 350 manual car,looking for a friends car to complete it..and if anybody has one for sale thanks..

it is 3rd week of November 1969 350 manual, also wondering what alternater they had someone told me they have a grey plastic on back,is that true, thanks.

ok thanks for your help, do you know the part number of the alternater, please..thanks again benny..

I agree. I've only ever seen and recorded 3 x different HT GTS350 number styles. The style mentioned above is the 3rd type and the most common.

This is going by memory, i'll correct later when I check the carbs in my shed if I'm wrong:

The first type is the same as what was on the last of the HK GTS327's, probably only applicable to the first handful of cars, possibly Pagewood only. #1-H5 had this carby. 7029283 with no picking slip code and no date code.
The second type drops the 70 so 29283 and adds the Julian date code. I have one of these.
The 3rd is as Geoff says above. I have one of these off a late 1969 into 1970 HT GTS350, it is 29283 ZC 1069. It is with its original manifold which also dates for the last of HT.

In theory there should also be a 7029283 ZC with a Julian date code underneath but possibly not. In general the 70 prefix doesn't seem to appear until close to Julian date code 2009, although I have recorded a 7029282 ZB 1359, but no photo so not 100% certain. In general you don't see manual HT 308 carbs without the 70 as these weren't around until late in 1969 which tells you that the 70 appeared prior to 308 manual, however you cannot rely upon that 100% for 350's as the 350 stuff appears to be far less Julian date codes ie came over in batches.

I think I've recorded the car already, 174-H5? Platinum with red trim?

HT ran into 1970 so this is in the middle, will probably have the carby as Geoff stated above (the third known type), probably even the Julian date code mentioned ie 0719.

Not interested in selling any HK-HG GTS327/350 stuff, impossible to replace. If I do end up selling them they'll be sold as fully restored and would be in the vicinity of $2500 each. The only way I'd part with one would be in some sort of deal with an original HK GTS327 carb off a Tonawanda engine, which despite being originally more common than the HT and HG carbs I've never managed to find one.

is the 1069 stamped down near the base of carby,thanks benny.

don't know much about the ht 350, its a rare beast,found a 7028212 E8DH, any idea,s might be of a yank car, thanks again..

Byron, I have a 29283ZC 0719 on a week 2 September 1969 Dandenong car which I'm sure is the original carburettor, so they were on
GTS 350 fairly early.

That would be pretty much right Geoff. As I said the first or the first few had HK carbs, ie 7029283. Then the next were 29283 with only the Julian date code, the one I have here is 29283 0159 (also have a 29284 0159). Later on they changed to 29283 ZC then the Julian date code, only three currently known: 0719, 1069 and 1359. I grabbed the 29283 0159 at a swap meet for the Platinum car featured on the front of Norm Darwin's Monaro Magic book, it is #4 or #5-H5. I gave it to Ben along with a mint US carby I found on the same day that had all the original bits on it (like fast idle lever etc), it is an auto version of the same carby - I think it is 7029212 or 7020212. The 29283 is missing a few external bits all of which are perfect on the auto carb. When Ben sold the car the new owner wasn't interested in having the original correct carby so Ben gave them back to me.

I have since picked up a few more US versions of the same carbies, in both Rochester and Carter versions. They are all the same for 327/250, 327/275, 350/295 and 350/350, just differ for auto and manual. I think one of them I got is off a 1967 L48 Camaro (350/295) or L30 Camaro (327/275) and the other off a 1969 LM1 or L48. I've just grabbed them for internal bits for GMH carbies as the US carbs can be found for a few $ at swaps. Unless you are doing a nuts and bolts resto there is no point spending over $1000 on a GMH carby when a US one is identical other than for the numbers. The 350 I have to go in the 5.0L HK GTS here will just get one of these auto US carbs (as it is getting a TH350). No point running an 307 and Powerglide when you can fit a 350 and TH350 without touching the car's structure!

We thought the same thing, with only about 500 odd manual 350 HT's made and sold here, and with 0719 carbs being used in September production you'd be looking at maybe 50 of the 29283 0159 carbs originally. Talk about Hen's teeth.
