Welcome. 7028251 is for an auto. 7028253 is for a manual. Note that it should have a 400 c.i. engine in it if it's a 442. Unless it's a Hurst Olds, then it got a 455.
Look for #'s on the timing shelf, above the water pump, below the thermostat housing.
A 400 would be 396026G a 455 would be 396021F. If he has a 7040257 carb in
his stash, I would be interested. If you can record the carb #'s when you go, we can
tell your their applications. Good luck and take your camera!

7028251 is the common big block carb for '68. It was used on everything except Toros. Stick shift 442s used a "253" carb but there seems to be some controversy on that & '68 W30s used a "254" carb. Like bccan said a '68 442 would have only had a "G" block 400 in it.

Thanks for the info! I have been rebuilding chevys for over 20 years, but this will be my 1st olds. Had assumed the engine on the stand was the original, which is the 396021f, the owner is the daughter, her dad bought it in 1980, and it was partly dissassembled years ago and is stashed around the barn. Dad is no longer around so I am trying to collect all the original parts which I believe are there from what I can see so far. I told her I would do my best to only take the parts that belong to the car. Now I have to figure out which motor is correct. I believe there were 2 other olds engines. On Thursday I didnt know where the vim stamp was on the block, so I should be able to figure it out.

Well most of the beast made it home today, i ponied up some extra money and brought home parts I was unsure of. I am going to be needing some help with parts id as I unload and catalog it. I did find the vin stamped g block, but as described must have spun bearings or something, it’s mostly a short block, couple of the rods and pistons were out, so I got the 455 I originally thought was the original motor too, it looks to have had some level of fresh rebuild and he had an electric motor rigged to the engine stand to prime oil through it. I’ll have to disassemble it to see what all has been done. thanks again for the help!
