Re: new 3.8 engine in 2007 wrangler
Normal rule is that angle x no of cylinders / 360 should be an integer for
any engine to get it well balanced, so v6s should be 60 degrees regardless
of whether it is for a front wheel drive or a rear wheel drive application.

DC Controled GEMA is producing 4 cyclinder "world" engines. Massive
public demand might result in Wranglers with one of these.

I do realize that a 60 degree is best for the V6. Buick demonstrated how
to make a 90 degree setup work with 6 cylinders, tho. After they
bought back the V6 from Jeep. The original setup for that engine was
rough. After they offset the crank pins it became smooth. I owned a 62
Buick special with the rough version and an 87 Park Avenue with the
smooth version.
It is hard to credit that the wrangler does not have room for a 90
degree engine tho. While a Chevy v8 is said to be narrow, can it be THAT
much narrower than the 4.7? The wrangler engine bay seems plenty big to
me. Never done an engine swap, I must say.
