Greetings ThreePonyStable.
I hope you have fun here. I sure do, but then I'm nuts.

I got three Ponys also. Well one of them might as well be a horse with no legs. (It doesnt run, and has rust problems, no brakes)
Anyway, about the 4.6, the 99 plus 4.6 are some kickin little motors. I've rebuilt pushrod V8's and love them everybit as much. I used to hate the 4.6, always called it turd and made fun of it. THAT IS UNTIL I rode in my friends 99 GT 5spd.
And now that we've modified them, they scoot now.
