I'm told it's a Series III SC 3800 out of a 2005 Pontiac Grand Prix but it looks so corroded I'm having doubts on my purchase. It does have the cover for the Series III but that's just sitting on top of the engine.
Stamped on the block is: Series 3800 12585792 The bar code on the block reads: BFL B0370147 Last 9 of the VIN stamped on the block: 251326433
I was thinking the same thing as Patrick, was the engine submerged? That or it has been left outside for sometime. What kind of deal are you looking at for it?
It came out of a 2005 Grand Prix with 90000 miles on it. That's 90000 miles driven in snow and salt of Connecticut roads.
I've since checked the oil and it is clean and under the valve covers it looks brand new. All the outer pulleys turn freely and I can't find any proof of water intrusion.
It's purchased, delivered to me in Central Florida, and sitting in my garage. Going to take some clean up but I am confident that it will not need a rebuild at 90000 miles.
I guess time will tell.
Anyway, I was just looking to verify that it was indeed a Series III.
Driven in the snow makes sense, I just looked at where you are and assumed you got it from around you. If I may ask what did you pay for the motor and shipping?
This is one example of why I tell people not to drive cars they love on salted winter roads. That one does look like it sat not running for a long time too.

The rust on the pulley grooves is the same as the rust on the faces....indicating it's been sitting a LONG time. Hurricane Sandy long time perhaps. Driving on salted winter roads would not do that.

I think it sat for a long time too. Internally it should be fine... I hope.
I think you can use the 3800 compressor ( if its still good) with some customizing of the hoses. I dont know if the fiero compressor would bolt up or not.
The engine looks like it may have been stored outside. Before I'd install that engine: 1. I would get a fiber optic camera , pull the plugs, inspect the cylinders. 2. I would do a cylinder leakdown test to determine their condition. IMO better than a compression test 3. I would fog the cylinders with oil and turn the engine over by applying power to the starter to see if it there is any grinding.
If all is good then degrease , wire brush and give it a fresh coat of engine enamel. Replacing the water pump is also a good idea. Good luck on the install.
