6.7 powerstroke beat everyone at their own game. They make more torque than a Duramax and Cummins, peaking lower than both of them. They party up high like a Duramax, and make plenty of torque down low, beating Cummins at their game.

The l5p blows head gaskets, (just like every other engine) eats lifters.. (gm switched to a Ls lifter design, while uncommon, they do still break cranks. 🫣 I would agree with you the 6.7 Cummins is probably the best engine of that era

I love a Cummins guy that respects a well built platform. That’s a true car/ truck car right there

There is a reason why people don’t use GM for hotshot driving they use Ford/Ram

sorry I'm still going to stick with a Cummins. ive had 5.9/6.7 Cummins,LLY and LBZ and a 6.0 and 7.3.......im still going Cummins. nothing,for me,beats the power and reliability HEAVY on the reliability. you can fix a blown head gasket on the side of the road in a 5.9. can't do that to any of the Vs. simple,not very many parts ,it's a tried and true design literally moving the world. from semis to buses to generators etc etc.

if it weren't for the stock pistons being terrible I think a 6.4 bottom end could give it a run for it's money

Can’t wait for the next upload. This has been the most entertaining L5p build with no gatekeeping information. Keep it up man!

need more fuel on the l5p platform and it would have the potential to bury every other platform. especially when you start talking about air limited classes. lbz injectors in an l5p would be golden
