GM V6 geneology questions...

1) Is the 3.5 used in Impala, G6, vans, etc. derived from the 2.8/3.1/3.4?
If not, is it an all-new design or is it from somewhere other than North
America?

2) Is the new 3.9 a bored and/or stroked 3.8, an enlarged 3.5, or what?

Thanks in advance for info.

I believe it is based in the 2.8/3.1/3.4 lineage, but with the various
bugs fixed (hopefully). I had a late 80s 2.8 in the past that was
pretty much indestructible. I've had a couple of modern 3.1s that were
the opposite

It's an enlarged 3.5.

No the 3.5 basic design goes back to 1955 to the 265CI V8 which became the
283, then the 307 to the 350. Then later 2 of the cylinders were removed the
engine was turned sideways and viola! You have a 3.5 V6!

Nope, that was the 4.3 - I'd be curious to get the straight scoop on
the 3.5 myself.

The 200ci (around 3.3L) and the 229ci (around 3.8L) are also in the
same line as the 4.3 liter or 262ci.

The 3.5 liter engine according to a couple of web pages I just read
was an all new design. Makes sense since it's a dual overhead cam
motor.

Taken from the page below.

"Ward’s, publisher of Ward’s Auto World and Ward’s Engine and Vehicle
Technology Update, cited GM’s all new 3.5 liter Twin Cam V6 and the
gutsy 5.7 liter LS1 Corvette V8 as among the world’s best engines for
1999."

You are confusing the 3.4/3.5 engines with the 3.8 liter engines.

The 3.4/3.5 are 60 degree angle motors (proper for a V-6) which have
little or nothing in common with 90 degree bank angle V-8s.

Doesn't. The 3.8 is a 90° V6.
