First off I hit the wrong number on my name, I have a 1968 delta with the 455, cause i know its going to look weird if a guy with a 69 is asking about a 68 lol.

Ok, first question: Is there a difference between a delta 88 custom and a delta custom?

second question: I haven't seen many 68's with the vinyl top or two door, is this a rare model year, and are the parts rare or pretty much availiable?

Most of the smaller things like the engine size I already know as the air cleaner says 455 rocket, and if it has a 2 or 4 barrel carb will tell you how many horse the engine puts out. I know that the it has the 4 barrel that it was an upgrade and has 395hp but if it has the 2 barrel it was the stock 310hp.

The car was given to a neighbor for doing some for my uncle about 4 years ago, and the guy drove it to his house after sitting for at least 15 years and there it sat. The reason for it sitting was there was a knock in the engine. I know that these engines were built to use different fuels for the different models so could this knock be due to the wrong gas being used? The guy who has it now said he never noticed a knock and he would let it run for about an hour a week.

Also I read that these cars had front disk breaks on some models, and I believe that the 88 was one that had front disk. Am I right on that or have I read to much and I am mixing things up?

I know I could just go look at the car, but it's still at the neighbors house and I really don't wanna start poking around on the car and then he deside he wants to keep it lol.

Any how thats all I got for right now, and I hope to get the car really soon. I'm one of those guys that always had newer imports so I never had to work on a real car, and I know that this is a long term project. I'm not looking to make it stock but I'm also not gonna make its custom just somewhere in between.

Thanks for you help in advance

 

The Delta 88 Custom is the same car as a Delta Custom.....

The car is not rare with a vinyl top or 2 door, it was just an option. Sheet metal parts and trim are the hardest to find as they are not made anymore.
Mechanical parts are no problem.

HP numbers change with 2 or 4bbl carbs but highest rated HP for that car would be a factory 4bbl and dual exhaust which would be rare.

A knock is usually serious but a tap usually is not. Neither caused by gas unless it was a pre-ignition ping or rattle and that can be caused by low octane gas.

All did not have disc brakes.... That was optional.

 

Thanks a bunch! I know that once I get the car I'll know learn more about it. I'm so glad that my grandparents always took care of it. All the trim is cherry and probably just needs to be buffed or re-chromed. I never even looked at the tail pipes so now I know that if it has the duel exaust what I got. My grandad bought it off a friend of his back in 71 for 1500 bucks, and up until it was given away it was, stored in a garage. Really just moved cause it took up too much room, and the guy that has it now just last year moved it out of his shop. I know i may have to replace the hood and pull one dent and thats about it for the body. All the glass is good, the dash looks good but the seats are ruined. Over all the car is in pretty much decent shape. The engine is no problem cause I'm going to trade the guy my 65 baja for some engine work.

 

455 4bbl on Delta Custom, was 365 hp/ 510 lbft torque.

 

You are right sir! The 390 hp was on the police package. See I have read too much and things are now getting mixed up. I went back and re read and now things are better lol.

 

Trust me, it took me awhile to get the correct info, going through brochures, manuals, etc. and learning how to decipher what was what over the years.

 

One thing I can't find are any pictures of the same year and style that I have. They are either 4 door's or convertable, I have found a few videos and a website of one but thats it.

 

Mine was my second car 35 years ago, and I didn't have the sense to take any photos.

 

The "Oldsmobile for '68" brochure has a 2dr on the cover, and a couple inside, it shows the bucket seat by itself, but not with the console auto. Can be found on ebay cheap.
