Seen several Cummins trucks break the 1k threshold without any building, just throw a piss load of fuel and air at it and watch the magic happen. Also, when Duramax cracks 4k hp let me know, but yeah, "Duramax runs ts"🤣

I mean the 6 speed Allison was never the problem so the trans is irrelevant

Everyone goes crazy for a stronger connecting rod, and a six speed but litterally every duramax before that has those capabilities. Lbz owners are a different breed istg
