I read a post here that ST-8 stated he installed some shift points in his trans and it shifted better than previous.

I have the dead dog 4.7 non-magnum. My issue is that this thing has the power of a 4 cyl on the freeway. It seems ok power wise , for a small V8, until I hit 60-70. no torque or power at all!!!
Its sittin @167k. Replaced the fluid about 1k ago. yy
Looking to repalce the exhaust and try to install an H pipe as close as possible to see it that helps the performance at all.
