  1. What kind of fuel milage did you get, I've got a 2018 5.3 with a mangusun supercharger.  I get 21.mpg hwy.  I want to do a cam swap but with premium gas I dont want to get 8mpg. 

  2. that's what we are going for. 500 rwhp = good enough. anything more is gravy
  3. LT4 cam...$140 delivered, ....better fuel lobe, and is a blower cam......not looking for 700 hp on a daily driver If I had to do the cam again, labor would be cut in 1/4.....
  4. I think that things are different on the 2105 with E92 ecm.... thanks
  5. all I have is crankshaft learn. when I click on it I get a message to slowly accelerate to fuel cutoff. I click on OK and do so...should I get a message that it was succesful? Also, is fuel cutoff 4k while in case learn?? thx
  6. I thought it was only when changing pcm's ?
  7. no, don't remove the engine, just the radiator and in my case , move the ac condenser out of the way invest $16 for 1 month of Chilton online, but ignore the first step 'remove engine' lol other notes: the oil pan does not have to be lowered, the oil pump stays put. alternator, ac compressor, water pump and front timing cover, including 2 bolts to the oil pan must be removed. The harmonic balancer is a tough one, it took a 700 ft. lbs impact gun to remove the bolt ( tty not reusable and a standard 3 jaw puller with short jaws to remove the balancer (it is keyed) when timing cover is off, rotate crank until cam timing mark is lined up either straight up or down and place a witness mark on something non moveable. This is needed in that the crank sprocket timing mark is hidden behind the oil pump. cam is held in by 1 bolt, very tight . It is part of what they call the cmp actuator and is not reusable (tty) rockers and pushrods removed, cam is spun to lift the lifters, 5/16" dowels to insure that they don't drop , timing chain tensioner has to have tension released, remove the phaser/cam sprocket and cam retaining plate and out pops the cam. without moving the crank, line up cam with the pin at 3 o'clock , phaser/cam gear with the arrow pointing to witness mark and assemble with new actuator bolt (tty) it's like any other ls cam change with a few twists.
  8. yes...lt4 cam, valve springs and injectors...similar to kb
  9. Will do.... anyone wanting to do this themselves, let me know, I might be able to answer some questions or fill in some blanks
  10. ran into this thread while trying to get info on swapping cams not much out there, so I jumped in and did it myself. cam, springs and injectors along with a 2.9? whipple, on my son's 2105 Silverado LTZ . I am in the tuning stages (hp tuners) Anyone wanting to do this themselves, I used a few tricks, not mentioned anywhere that I've looked. Started by buying a 1 month subscription to Chilton online. Some good info, but cam swap begins with removing the engine....lol
