Gauging interest in a possible trade. I have a 1968 manual trans Quadrajet that I reciently aquired. I have a 68 442 with an automatic. I would consider a straight across trade for the same as mine but for an automatic. The numbers on my carb are 7028251. I am looking for 702825X-even number

 

A '68 4-4-2 with automatic transmission comes with the carb you have - the 7028251. There's lots of research on this site about this subject. It seems that, most of the time, the automatic transmission carb ended with an even number and the manual transmission carb ended in an odd number. This is not true for the '68 4-4-2. There were some '68 4-4-2 cars with manual transmissions that had a 7028253 carburetor but a lot of those cars also had the same carburetor (7028251) as the automatic transmission cars. My advice - keep the carb you have. It is correct for your car.

OK. Thanks, Randy. I was in a quandary about this. The carb I have is in good shape and I was just going to rebuild and run it, but thought I would go out for the even number and see if someone would trade. I think I will take your advise and just run what I have.

 

For anyone looking, I withdraw the offer.

 

Also, check the bottom plate, driver side on the vertical edge towards the rear, and you should see a 4-digit julian date code (3 digits giving the day of the year, from 001 to 365 or 366 on a leap year, and a single digit indicating the year, where 7=1967, 8=1968, and so forth). If your carburetor hasn't been messed with, that with give you the date the carburetor was manufactured. You can check that date against the manufacture date on your cowl tag. If the date on the carb is before the manufacture date on your cowl tag (most of the time within two months but sometimes known to be as much as 6 months before), that means your carb could be the original to your car. The carb on my car was missing when I restored it and I had to find a 7028251 with a manufacture date before the date my car was assembled for it to be consistent with all the other engine parts and the assembly of the car.

Again, Thanks Randy. Excellent info
