LC1 Posted January 18, 2022 Share Posted January 18, 2022 I have a 01 ch613 350hp with 10speed trans, 700k. Might have to pull trans to rebuild couple “forks/gears” (pops out). At this time would it be worth switching to a 13sp to “livin” up the trk a little since it’s only a 350hp. Looked into turning up to 427 but that’s 5k also. Otherwise Jst put the 10 back in it. Didn’t know if 10 to 13 would help that much?

67RModel Posted January 18, 2022 Share Posted January 18, 2022 Having more gears on the high side is always more helpful than not having them. If you are purchasing a used transmission from a salvage yard there is no guarantee about what you are getting. If you are getting a reman unit they probably will not accept your 10 speed as a core so there may be more cost involved. the 13 will require a different stick or a at least a new knob than what you have in addition to a little more air plumbing to the knob. Also, the 13 speed is longer than a 10 speed due to the auxiliary box. You will need to have your drive shaft shortened if you switch to a 13. I'm not sure if the mounting locations and cross members are the same for each transmission but that is another thing to check before you make a decision. Do you have an Eaton or Mack Transmission currently?

james j neiweem Posted January 18, 2022 Share Posted January 18, 2022 What options for HP increase are there? E7-400, E7-427, E7-454? Turbo and injectors I assume.🙂 Quote Link to comment https://www.bigmacktrucks.com/topic/69078-01%E2%80%99-ch613-e7-350hp%E2%80%A613-spd/#findComment-487356 Share on other sites More sharing options...
LC1 Posted January 18, 2022 Author Share Posted January 18, 2022 Eaton 10 currently Quote Link to comment https://www.bigmacktrucks.com/topic/69078-01%E2%80%99-ch613-e7-350hp%E2%80%A613-spd/#findComment-487360 Share on other sites More sharing options...
LC1 Posted January 18, 2022 Author Share Posted January 18, 2022 I was told from Mack dealer for our yr model it would take turbo and injectors and $60 program and that would make it a 427. I believe the turbo was basically $3K I had talked to others that had couple yr older and bumped to a 400 (which helped a lot they said) with Jst a program I believe for $1000/2000 but I assume that’s the difference in a 98 vs 01….??

Joey Mack Posted January 18, 2022 Share Posted January 18, 2022 (edited) The 400 seem's right, but I thought you have to change the cam key for timing? (Advanced) to go to 427 and up?... Some others will add to this... There's nothing wrong with the 400... it pulls great...Jojo Edited January 18, 2022 by Joey Mack More content needed 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69078-01%E2%80%99-ch613-e7-350hp%E2%80%A613-spd/#findComment-487367 Share on other sites More sharing options...
james j neiweem Posted January 19, 2022 Share Posted January 19, 2022 E-7 400 seems like a good compromise between power and longevity. What is the torque on a 400 E7. 1500-1600? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69078-01%E2%80%99-ch613-e7-350hp%E2%80%A613-spd/#findComment-487417 Share on other sites More sharing options...
880joe Posted January 19, 2022 Share Posted January 19, 2022 Being an 01 it could be a CCRS engine that wouldn't require a cam key change and the 400 puts out 1460lbs of torque Quote Link to comment https://www.bigmacktrucks.com/topic/69078-01%E2%80%99-ch613-e7-350hp%E2%80%A613-spd/#findComment-487424 Share on other sites More sharing options...
Joey Mack Posted January 19, 2022 Share Posted January 19, 2022 Hi 880 Joe.... I thought CCRS came out in 02-03.?

Onyx610 Posted January 19, 2022 Share Posted January 19, 2022 (edited) For some reason I think there were some etech ccrs engines floating around before 02.

880joe Posted January 20, 2022 Share Posted January 20, 2022 I've had a couple of 01 visions that were CCRS and a couple that weren't Quote Link to comment https://www.bigmacktrucks.com/topic/69078-01%E2%80%99-ch613-e7-350hp%E2%80%A613-spd/#findComment-487455 Share on other sites More sharing options...
