Question: 6.4 vs lmm?

[zf>allison]

Buddy barney has a crew cab dually 6.4 that had tuning, stock exhaust, I think it had an intake maybe and he hit 13.6 13.7 repeatedly. He said with the tool box and shit it's over 9k. But he got scared of reliability and traded it in on a 6.7.

I know this is older but the latest 7.4s were pretty quick. Buddy had one that I could actually call fast! Also a whole different world using a high pressure oil pump that pressurized the fuel. I think it was a unique fuel delivery.
