  1. Can someone give me an idea what's wrong with my truck? I just put a remanned 350 vortec bored 30 over, with an RV cam. I've replaced just about everything you could think of. First issue that started was it was popping codes for timing advanced 25 degrees. Had to take it to a shop to habe it timed with a computer. Now the EGR valve code is coming up all with 3 oxygen sensors showing insufficient activity. Mind you, my truck is straight piped with true duals coming out the passenger side by the tire. I just had it done. So what is happening now, is when I push the gas, my truck barely wants to go. I have to ease into it. Parts store said it was the EGR valve, replaced it, still doing it. Seeing if anyone out there knows what I need to do next. Replace the oxygen sensors? Will that fix it? I also replaced the oil pressure control sensor on the back of the motor by the rear intake? It was fried before I out the engine in again. I also have 0 oil pressure on my gauges now but I have oil. The truck drivee fine other than when I hit the gas pedal it barely wants to go. Any help would be appreciated. Thanks.
  2. Thanks for the reply sir, the cams already in and the new motor is halfway done, the rv cam in there now is from summit racing, and like I said it's bored .30 over. The next thing I was gonna do is the exhaust and out shorty headers on it. Get that 25% more power. But I'm hearing this computer is going to mess it all up. I'm not sure what to do. Some people said as long as it's not a choppy cam, I'll be okay, others are saying it's a big deal and you have to get it tuned.
  3. Hello, so I'm replacing the stock chevy 350 vortec. I'm replacing it for a chevy 350 vortec long block, bored .30 over with an rv cam. Do I need to do anything to my computer??? Is it going to cause me problems??? I'm hoping someone can give me some advice thanks.
  4. Okay so as long as I stay 2.5 in the front I should be good until I go bigger with a suspension lift correct?
  5. Okay people, I have never done a lift kit yet and I have heard alot of pros and cons so help me out here. I have a 1998 chevy k1500 silverado edition with a 5.7. I have wanted a lift for awhile well guess what? I got one for christmas and it's just a starter. I have the new slightly bigger than stock, torsion keys and rear blocks. I have heard once you put this on, you start eating parts. So I guess I'm asking, what's the best way to do this? Put the lift on and only crank it to 2.5? Supposedly you can get a 3 inch lift out of the front, but not suggested. Any help would be great, thanks.
  6. Okay, my question is that i am looking to straight pipe my 1998 silverado i just bought with a 5.7. I used to own a 2001 silverado but it was a 4.3 v6 and that was straight piped but i got horrible gas mileage. i am looking to get an aggressive sound out of my 1998 i just bought and was wondering if anyone could give me some tips on how to get that sound without killing my gas mileage and possibly avoiding a new muffler.
