  1. Ok, I'm sure there is a way to send a message direct from person to person so off topic conversation doesn't bog down an ongoing topic, someone gimme a hint as to how, or maybe what to look for to do so

  2. Btw the trans in this truck is a 4500rds, not a 3 series, that model, in that year truck, was available from Mack behind the 427 and lower ratings, but the 300 and 375 versions were supposed to be mapped for best performance behind the allison.
  3. I think I'm going to try the 375, but I believe I'm going to want more in the end. If it was a truck that the drivers use, I would be reluctant, but it's only me, the repair bill check writer (and my personal truck) so I believe it wouldn't be abused. My local Allison shop head tech is a personal friend from high school, he feels confident, on this model Allison, to around 1700 foot lbs owner driven
  4. On the passenger side, standing on the ground, there is a rubber sleeve that couples the A/C blower discharge duct to the inlet side of the evaporator, a Phillips screwdriver and a few minutes time removing the inlet duct(slide the rubber to the right or left to allow the removal of the duct, can't remember which way) and your staring at the inlet side of the evaporator, which I'll bet a donut on, is nearly 100% plugged. Clean it with a vacuum or wash it in place. One of my old drivers likes riding with the window down, A/C on, dusty air through a cold evap coil, damp from the S.Louisiana air makes a muddy mess! I have to clean his every few months, complaint from him? A/C not hardly blowing
  5. That would be great, I've been told 427 up is where it it takes iron over electronics
  6. Yup that would be her! I like the ole gal, tough as nails, but when she is tagging the excavator, she is around 81k, could use a bit more umph, but when she is at 81, and not pulling, it's dangerous because it's unpredictable, you may pull out and be fine, or you may pull out with maybe 100 hp and that seat pucker factor comes into play

  8. Mackpro, my last 6 is 010433 on a 04 cv713, and thanks a million ahead of time! MackTechnician, im going to try to get a rock 5 inch exhaust with a pyro port, can i consider 900 degrees a safety point not to exceed??
  9. Ok, thanks!
  10. Thanks for the CCRS schooling! Has any issues been noted when using a non-AI exhaust manifold without the 460-high heat center section on a motor with tune, injectors and turbo? And I caught something rereading the whole post this time, I've been having an intermittent low power issue where I get low boost, low power, then suddenly, like a switch is flipped, engine pitch changes, turbo spools and the missing power is back, like what was being described as pinched fuel line in the post, sounds like a software update may be needed
  11. I have a 04 granite, my buddy has a 07 granite(cv not gu) and I like the headlights on his, anyone know if the 07cv hood will fit a 04? Im re painting this fall and would like to get the newer style lights
  12. Ok ok, if this ground wire connection is bad, it kills the whole panel?(except air press) I'm fighting a dead panel on an 04 granite, I can wiggle or side load the plug on the back and get it to hit and miss, but it's all or none(gauges/lights/buzzer) and I wasn't sure what to look to
  13. Did Grand Rock assign part numbers that others could use to put the 5 inch on other AI applications? And what does CCRS stand for?
  14. Btw I might not have fully explained, since imma have the manifold off for gasket change, ideal time to change to non AI exhaust manifold right?
  15. 2004 granite AI300, getting ready to change the exhaust manifold gasket. I've read on here that the AI motors use a smaller more restrictive (maybe for more back pressure for the AI EGR dual bump cam?) manifold and that replacing it with a non-AI manifold reduces oil sooting and helps exhaust flow (bigger injectors coming!) does anyone know what part number I should buy for this?
