Alright, I'm going say that instead tomorrow.

I have spend some time to research for 3800 engine. They are very nice and fast of course. It is nice to know that new engine won't cause any fire like old cars. Also, tranmission problem cause by 50/50 chance. Some abuse or some care. Since, I will care then I'm sure it will be fine. The FWD thing... lol I guess that's life.

I own 3 3100 engines from 1997 Oldmobile Cutless Supreme (sold it 2 months ago ), 2003 Pontiac Grand Prix (summer) and 2001 Pontiac Grand Prix (winter).

History about 3100... I meet that engine first time in April 2001. I like it very much. It was much better than my 1st car Chevy Corisca that I wrecked it. I don't remember what kind engine that car have lol... 3100 engine is pretty good. My old car Oldmobile Cutless Supreme have over 250K mileage when I sold her away to someone. My summer car now have over 100K. My winter beater is almost reach to 60K mileage. When I took my car to service for 100K mileage. This guy told me this engine is very good shape. I told him I changed it every 3,000 miles. This guy told me that's really good. It should last you forever if you keep doing that. It is feel good to know that. It is only one problem with my engine that gasket blown but it cause by coolant. I already send gm coolant lawsuit that everyone complain about that 3 weeks ago. I might get all of my money back but I have to wait and see.

Since my 3100 engine is very good shape. I hate it waste if I throw it away for nothing during swap for new 3800 engine.

I'm going to keep my 3100 engine. Yeah, I can't hear but I will probably get loud booo from grand prix crowd :p

BUT..............

Like AustinGTP.... He blown engine like May or whenever and he use it other chance. I believe his car is 1997. He is pretty good job to keep body clean over 11 years. If something happen to my engine then it will be good chance that I will swap new 3800 engine. My car is 5 years old and over 100K mileage. It will take some time to see what happen in future. Since GM stop making 3800 engine. I think it is safe to say I might not get any new 3800 like 5 years later. Who know how good my 3100 engine. It is still good right now. Sorry long type but want to tell how I feel about 3100 and 3800.
