2008-10 Ford 6.4 to Cummins Conversion aka Fummins
These “fummins ” conversions are one of our favorite builds to do. We practice what we preach; the owner’s truck is a 2008 F350 6.4l converted to a 24v 5.9l Cummins.
These 2008-10 Ford Super Duty’s with the 6.4l Powerstroke are fantastic trucks, but are notorious for their catastrophic failures . They are gorgeous trucks with a very powerful engine, until the 6.4l Powerstroke”gives up the ghost”, normally at a very early age. The dealership will charge upwards of $20k to replace the factory engine. This is not acceptable when the new engine will only last on average 80,000-120,000 miles, with the OE emissions and tune.
Why is it that the 6.4l fails so early?
1) A very poorly designed emissions system with an extremely aggressive re-gen cycle
2) Another reason, is due to a temperamental high pressure fuel system. The injectors in these trucks have been known to fail and burn holes in pistons as well as cylinder walls, causing a very costly overhaul. Sometimes not even a repairable engine block, even with a dry sleeve.
Not to fear, these issues can be avoided if addressed at an early enough age; check out our service page for our 6.4 service.
