BUILD INTRO: David Warren’s 1971 Ford F250
We’re converting this classic 2WD '71 Bumpside into a modern 4WD monster.
The Specs:
* Drivetrain: 6.0L LS engine mated to a 4L80E transmission and NP261HD transfer case, managed by a Holley Terminator X Max.
* Super Duty Axles & Factory Integration: Front & rear late-model Super Duty axle swap, Super Duty steering box, factory steering linkage, and complete hydroboost brake system.
* In-House Fab & Suspension: FOX coilovers and custom front & rear 4-links mounted with bracketry designed in-house and cut by . All fabrication and TIG welding performed 100% in-house.
Modern capability meets classic Ford style. Follow along to keep up with all the remaining custom touches as we finish bringing this truck together at Holy City Rod n Custom!
