Hi, I'm new to this forum, have recently purchased a 1970 W30, car is all
original except for the carburetor, it has 1971 unit on it. I'm trying to decide to either have this one rebuilt or try and find and an original. I know they are rare, but I have found a few suppliers saying thay have them.
Anyone have any thoughts ?
Thanks
Bill

First of all, no fair braggin on your W30 w/out posting some pics..
Second of all, lets see...ALL original W-30, or kinda original...the upholstry is not what made the W30 legendary...it was the motor. Finish out your motor.
You just bought a W30, I know you can afford a carb.

Save this thread and let me know if you buy a 1970 carb if you'd want to sell the 1971 carb.

You need to be very careful here. Lot of these cats who claim to have them have garden variety carbs that have been restamped with the W30 application numbers. Yeah, they'll LOOK right, but they won't RUN right on that wompus-cammed engine.

If you opt to have the 1971 unit rebuilt, I highly recommend Greg Kalkhoff. He understands Oldsmobile and Q-Jet and when it returns it will be restored, not just rebuilt.

I can second that! I have heard nothing but postive things about Greg Kalkhoff aka Sparky.

I'd leave the 71 as is until you find a correct one, as mentioned be careful but there are a decent amount of 7040258s around of course unless you have a 4-speed then that's even harder to find

Thank's for the advice, I'm new to the Olds world, I had two W30's 30 years ago , so I'm just trying to get a feel for what parts are available now. The carb is the only thing on the car that's not correct. I had feeling it would be tough to find one, I just didn't know if the ones that some suppliers are offering were legit are not.
I'll contact "sparky"

Danny Sarvis is another good resource to rebuild Q-jets. He is an off and on member on our site (70Wcars). He rebuilds Q-jets from time to time for members. His prices are decent and he is a guru when it comes to Q-jets.

I have both 7040258 & 7040256b carbs,but I also have the cars that they go to.The restamper guys don't seem to realize that they used certain casting numbers for the top,body,& base.These are not the same pieces as a Q-jet from a 350 or a common 455. The other important note is that they only made these carbs on 4 or 5 different dates,meaning there are only 4 or 5 correct dates for these carbs,so you can't just pick a number out of a hat. These carbs were made in batches,on certain days.You would need one made before your car was built,to justify getting one to finish the job.
