Ford Engine HELP...

The PG will absoluteley kill the ets. I cant believe someone told you 3.73's were the way to go. With a 28" tire I would recommend either a 4.56 or 4.86 depending on how high you want to spin it. The other thing that draws a red flag for me is the mph you have seen and I would MAKE SURE the valve springs are up to snuff. Just because you dont hear a audible "valve float" doesnt mean they arent out of control. As others have said the dyno may help but if it's still in the car I would try the new rear gears first WITH a C4. 3.73's had to be killing that poor thing. Hope this helps.
