CM870 to CM871 Conversion

[RAAK]

Hello everyone. Just got my registration code 30 min ago and I’m glad to be here. I have been in trucking since 2008 but I got out of it for a while when my boys were younger. I recently got back in a truck doing local deliveries and the bug has hit once again. I am going to buy my first truck very soon and wanted to get some info/opinions on what I want. I will be pulling dry vans at 80k and under and I don’t have any desire to go to California. I have a special place in my heart for the International 9400. It was the first truck I went on the road in and it has been my favorite to this day of all of them I have driven. I have been reading on this forum and watching Rawze on YouTube for 3 weeks straight. I really want to buy a $10-12k truck and go through it so I know what is in it. I know I want a demandated CM871, 13 speed, and 3.55-3.79 gears. The problem is I don’t know if International put the 871 in any of the 07 9400 trucks hence the title of this thread. I live in north Alabama so getting to Mr Hagg in GA is no problem. I’m 2 hours away max. There are plenty of 870 9400s out there. I know I read somewhere that Running rough has done this conversion. I am buying a truck knowing that I will be putting $30k+ into the engine immediately so I am not too worried about the additional cost of the conversion compared to just doing the 870. What is involved in doing this? I know the turbo and ecm. Would i have to get a complete 871 or would I use the 870 and get the additional parts? I should have about 60k to put into the truck. I will be buying a laptop, inline6, and insight. I already have lots of tools but I will get any additional tools I will need. I understand that I will be giving up a little fuel economy with this truck vs a Prostar but at least it is semi aerodynamic lol. I’m not completely opposed to a Prostar but if I’m doing this and putting up the cash I want to get what I want. I’m sure I have forgotten something and I’m sorry if I’m scattered all over the place but I’ve never been know for my writing skills lol. Thanks y’all.
