Thanks is there anything else you can think of that could be causing it to knock. The knock speeds up with the rpms. In other words the higher the rpms the faster the knock.

rebel, if it is a knock, it is most likely a stretched rod which means you will have to have the rods resized and new bearings installed.
One way to check to verify it is a rod, is to disconnect one spark plug wire at a time until you no longer hear the noise. Obviously you re-connect each wire after each try. heheheh, otherwise, most certainly the noise will disappear after about three disconnects! hahahah! Ha ha, I crack myself up!Objects in my rear view mirror are a good thing unless,.... they have red and blue lights flashing.

Thanks TyphoonZRBrad
If It runs like a deer it's to slow.
Going slow is just a crutch for the people who can't deal with real power.
If it ain't classic or Chevy it's junk.

Also check the flexplate. Some of the old 307s snapped their flexplates which sounds like a knock. If you need more referance on the SBOs, I know a little about themRight engine, Wrong Wheels

Thanks man
If you woulda said flywheel I woulda been like ight. I feel stupid for it but I've never heard them called a flexplate Thanks though I already checked that and the "flexplate" is perfect. I'm starten to think its a bearing though anyone else have any suggestions let me know I'm confused so bad right nowBrad

My 86 Cutlass Salon
I have been needing to gas it a lot to start it, and when it does run, it chokes, so I am thinking it needs a new oxygen sensor. What do you guys think.

Doubt it. The 02 sensor on the feedback carbs has very little to do with the actual starting. My suggestion would be to pull the engine codes. If you get an o2 code, fine, but thats probably not it. Now when you say gas it, do you mean pump it or do you mean pour gas down the carb?Right engine, Wrong Wheels
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
