The swap requires a new dogbone, but not a new front engine mount.

I think that on my 87 I only had to shave the stock mount but on 88's it's different.

Hello Lou, I am just a big fan of the 60 degree V6 and the aluminum heads intrigue me quite a bit. Ultimate horsepower gains don't mean much to my kind of driving and I would just like a more updated engine with some more punch. It is just a personal preference and keeps in line with the original GM design. I hear ya though. |

The 60 degree V6's do sound *much* better than 90 degree v6's...[This message has been edited by lou_dias (edited 05-12-2020).]

Hi Fred, the 3.8 N.A. is a fantastic engine to go with. Well documented, relatively cheap parts. I am doing a 3.8 SC series 2 swap right now and it has been a relatively smooth process. Finding one with about 150,000 kms seems to be the relative low mileage ive been seeing. These engines are well built with many going above 400,000 km easily.

Here is a bit of an estimate (Approximate)
3.4 (~160 HP) 94-94 Camaro
3400 (2000's grand am) (~170 HP)
3.8 Naturally Aspirated ( Gen 2) 97-04 Buick Rivera (~200 HP)
3.8 Supercharged (Gen 2) 97-04 Grand Prix GTP (~240 HP)

Hey Marcus, thanks for the info. As I mentioned to Lou though, I am a fan of the 60 Degree V6 and with the higher compression and much higher flow of the splayed valve aluminum heads plus a weight saving it is quite easy to get around 180 HP and this is fine with me. A good bump in torque too. This engine will sound wonderful as well. For my type of limited driving around the backroads of Ontario I think it will be an excellent choice.

3500 (LX9): 205 HP
3500 (LZ4): 215 HP
3900 (LZ9): 245 HP
Also, I thought the 3400 was 185ish HP...

Hey Fred,
Not sure of the differences would the 3400 suffice? seems easier to find.

Also consider there are different HP ratings for the same engine depending on the vehicle. The highest HP 3400 was on the montana van, which makes sense considering how big it was.
The LZ9 ranges from 227 - 242 HP but i see what you are saying. Im curious of the torque differences between the 3800 SC and the LZ9 3900

The L67 will make WAY more torque because, well, it's the same displacement but supercharged. The LZ9 makes more power than the naturally aspirated 3800 because the heads flow better and it has a bigger cam.

Ive never seen a 3900 in person. I have a friend who is doing a swap right now from an Impala like you stated. Looks interesting!
