So I switched out my Isky cam for a TFS #1 cam. I use to pull 18lbs of vacuum, but now I pull about 10lbs.... I thought that lobe seperation determined the majority of vacuum and this cam is suppose to have good pull. I have drove it for a little while and it sucks, I have lost power and got beat by my brother's stock 5.0. Im assuming I have a leak somewhere but I don't hear anything. Timing is set at 12 and from what I can see everything is hooked up. Also, this thing is running rich, it smells like a bucket of gasoline is just sitting under my car and a midget with a fan is blowing it in my face. What do you guys think?
