Yep, you got it Frank! I've got the proof. One thing , the 4.7L is only
around 50 pounds lighter I think?!(than the 318), Anyway, 100 pounds is only
good for about a .10 sec at the strip. I don't know what the Transmission
weight difference is for the Auto and the Manual, but if I had to guess, I'd
say the manual trans weighed more because its cast, and not aluminum. I am
going to Dyno my truck soon and see what the real HP is, I am some what
skeptical of the 235 rating of the 4.7L, reason being, my truck consistently
runs quicker than the stock RT's. So what I'm getting at is I personally
think the 4.7L may be producing more than 235 hp. Just my thought, We shall
see, I am scheduled for the Dyno in February. The Dyno sheet won't lie!!

<When the 4.7 is equipped with a manual tranny, and the driver can actually
<DRIVE, and all other options being equal, the 4.7 will come out ahead in a
<race. The reason being that the 4.7 has only 15 less hp than the 5.9 but
<weighs over 100 pounds less. That's just the engine, not sure about the
<transmission and rest of the components.
<The 4.7 has got great power for it's size, and it'a a "rev-happy" motor.

>Question: Why is it that the 4.7 SLT version out runs the 1999 R/T 5.9?
