I LOVE a flat torque curve. It means you have power whenever you need it, wherever you are in the RPM range. I particularly like how it slowly rises to a plateau instead of a quick peak and tapering down. Yet another reason to love the inline-sixes!
Just out of curiosity, which gear did you have it in? I'm assuming this is a chassis dyno.
after i get my 5.8 swapped into my new 85 i am gonna run down to the local dyno shop and take a pull or two just to get a baseline. only thing done at that time will be jba shorties and 3" exhaust without cat and flowmaster. ill probably be running the 31's with 3.50 to
