Re: More New Scrambler Details
You're welcome. Remember, the question of V6 vs I6 isn't, which is better?
The question is, which is better for a particular application?
I have a BMW with an I6 motor, and it revs to 7000 rpm, the I6 in my Jeep is
screaming at 3500. The BMW will easily stall from a stop sign on a hill but
it will cruise for hours at 100+ mph. The Jeep will pull stop signs out of
the ground at idle, even on a hill, but it resists any attempt to go faster
than about 70 or 75, and it prefers to cruise at speeds in the 65 range.
So, the I6/V6 question/debate must be refined to the specific V6 and I6
involved. In the case of the Jeep application (particularly the TJ), the I6
is the preferred configuration for the reasons I told you about.

Re: More New Scrambler Details
I understand that it is not really the orientation of the cylinders (V-6 vs
I-6), but the bore/stroke. Supposedly (given same bore) a longer stroke will
produce more torque & a shorter stroke will allow quicker rise in RPM. It is
also my understanding that, traditionally, I-6's (in America)have been
produced with the longer stroke & V-6's have been short stroke. It would
therefore seem that a low RPM, high torque V-6 engine could be produced
but, traditionally is not. I would think that the shorter crankshaft of the
V-6 would be a plus. I also read that the reason that Chevy built the HiPerf
I-6 because it was cheaper (one head, one set of cams, etc)

Re: More New Scrambler Details
I understand that it is not really the orientation of the cylinders (V-6 vs
I-6), but the bore/stroke. Supposedly (given same bore) a longer stroke will
produce more torque & a shorter stroke will allow quicker rise in RPM. It is
also my understanding that, traditionally, I-6's (in America)have been
produced with the longer stroke & V-6's have been short stroke. It would
therefore seem that a low RPM, high torque V-6 engine could be produced
but, traditionally is not. I would think that the shorter crankshaft of the
V-6 would be a plus. I also read that the reason that Chevy built the HiPerf
I-6 because it was cheaper (one head, one set of cams, etc)

Re: More New Scrambler Details
Hi Dave,
You're thinking of the obsolete Buick V6 from '61, which GM just
lobbed off a couple of cylinders and left the crank quartered, when GM
bought the engine back they corrected that problem, and bent the crank
in thirds. I can tell you the Ford V6 uses a separated journal and throw
for each cylinder.
