Ya I’ve noticed, it pulls good down low. Usually can take off in a higher gear, but it falls on its face north of 1700 it feels like. Noticed it today movin a 320 cat ex. Im gonna do all the bearings in the lower end, before I throw more power too it.

I’ve had people me ruin putting 460 program in. I’ve gathered over time though reading on this forum and a few others that the 427 seems to pull better. Im sure due to a flatter torque curve and build its lower in the rpm Range. Not trying to kill my engine, I’m gonna do rod and mains when I got with whatever I decide as added peace of mind. Imo more power never hurt anyone, as long as its used wisely.

Nice, so foregoing the injectors and turbo for the box is a safe and reliable option? I’ve seen them before, just don’t ever hear much Feed back on them.

I’m new on the forum, and an by no means a subject matter expert on Mack. My knowledge on Mack’s is minimal. I currently am running an 03 ch613 with a factory rated 427 E7. This particular truck is primarily used for pulling an end dump, but does on frequent occasions haul Heavy equipment. The plan is to upgrade to stage 3 injectors from Rochester diesel. My question is, is there a better/cheaper option as far as a turbo upgrade to compliment these injectors. I’ve been told that swapping a Detroit turbo can be done and that they perform well. Is this a viable option as far as bang for buck/ease of installation. Any insight on this would be greatly appreciated.

It’s a 10spd. it’s not a need, more of a want. I’m used to big cats. Now I do realize that it’ll never be a cat by any stretch of the imagination. But IMO driven responsibly, more power to a certain extent is never a bad thing. Plus I can’t leave anything alone. If I can have more without damaging anything, I want it.
