I was pulling my camper last night, 17' single axle, and started dropping power and eventually started back firing through the carb. Pretty much lost all power. Long story short after unhooking the camper I was able to drive it a little way to a truck stop and at that point I gave up on driving it home. I built this motor about 2.5 years ago and it has about 15-18K on it. It has never had the power I felt like it should have and has always seemed sluggish. Thats why I went ahead and tried to drive it I figured if it came apart completely I would have a good excuse for starting over (don't tell my wife that part) . Anyway I am pretty sure its the cam. Oil pressure is good no noise in the bottom end I do have some tapping in the valve train. I have lost a lifter, a lobe off the cam or bent a valve something. It is idling very rough, not to the point of dying just rough, you can tell it is down a hole or 2. I plan to replace the cam, anyway due to lack of power. Give me some suggestions on what cam for a 350 in a 1/2 ton Sub, headers, edelbrock performer intake, 700r4 3.55 gears. I actually had a performer cam in it at one time and I wasn't impressed with it. I am almost to the point of selling my Sub and my Jeep (don't go there not the topic at hand LOL) And just keeping the 2000 Ford Explorer 5.0 that my wife just quit driving. Something has to go Explorer or Jeep/Sub, I know where you guys stand what can you do top covince me to stay on the straight and narrow Chevy way?
