This would be something we want to have machined in batches, otherwise it will be way too expensive to run one off's. I'm expecting the honda to be a go because there are so many but we'll have to see for the ZF-6. I'm assuming your refering to the 6sp manual in the F350 super duties?

Based off of a DX or LX Civic trans with a 4.08FD, changing to a .600 5th gear would yield 69mph at 2500 RPM based on a 22.8" tire diameter. Many of the 2-valve and VTEC-E engines make good torque at 3000rpm and should be able to pull this gear on the flats.
