Oh yah in no way am i even considering it lol. My buddy is just getting his heavy equip degree and rebuilding them and we were just BSing around with the idea. again "Not going to do it" lol.
Does anyone know if GM is still making the 8.1 with an Allison trans



They did but, not anymore. The 8.1 and DMAX could be had with the Allison but, the 6.0 was 4l80E (now 6L80E, I think is the name for the new six speed heavy duty non-Allison?). I could be wrong but I think the 8.1 was also available with the 4L80E too but, I doubt there musta been many takers on the 4L80E with having the Allison as an option!!! As mentioned though, no more 8.1 anymore.![]()
