Trying to identify my Buick engine: HELP!!!

Hi everyone!!!

This is my first day with Team Buick and I'm looking forward to gaining some knowledge regarding my new project. I currently have a 1985 Buick Regal that I am going to start working on. The first thing I want to do is identify which Buick engine I am going to be working with. The engine is not the original engine (which is the whole purpose of this post!!!). I've looked through all of the information posted on the site and was not able to come up with an answer. I'm hoping one of you would be willing to help! The paint color of the engine is blue. It's a V8. I've checked the driver side of the engine and was able to find "C208" stamped near the front spark plug. I was also able to find "DN" located near the back spark plug. Hopefully this is enough to at least get us started with identifying this animal! Please let me know if any additional info is required.

Thanks and hope to get an answer soon!!!

How about a picture? is the distributor in the front or back.

and the cheat sheet told you what?

Distributor location, valve cover bolts and transmission bell pattern can tell you what most options are going to be .

IF it's a GM engine.

Oldsmobiles have the oil fill tube that dumps into the timing cover.

Pontiacs have the passenger side cylinder bank forward of the drivers side.

i believe some of the newer "corporate" 350 v8s only use to valve cover bolts.

a vertical distributor shaft at the front of the engine is usually either a Ford or AMC.

The distributor is located at the back of the engine. I will get pictures posted later today.

Here are a few pics

Looks like a Pontiac engine. In those days there was only 1 Pontiac v8 engine built the 4.9 or 301. They were real dogs and didn't respond to performance mods. Too much stroke not enough bore and very poor breathing characteristics. It can never be built in much more than a boat anchor.

If a zero performance engine is good for you they did run ok for around 150k with good maintenance. - Bill
