Hey everyone. I've got a 1997 f250 thats getting a 12v cummins and an nv4500 swapped in. The 12v is out of a 1994 ford b-series bus. I got the engine in her yesterday but theres a few things that are on my mind. For one I was wondering about how the best way to run the brake booster would be and I was also wondering how I should go about the clutch. I already have a south bend single disc sitting in the shop but I'm unsure of what pedal assembly and hydraulics I should run. The guy I got the tranny from threw in the dodge lines and the dodge pedal assembly but I was thinking that the ford pedal assembly might be a better application for this. Any advice is appreciated. Thanks.

 

For the clutch, use the Ford master cylinder and the Dodge slave cylinder....if I recall correctly, the Dodge line should plug into the Ford master cylinder. If not, a custom line could be made to mate the two. I'm running a Getrag 360 right now, and the Ford master pushes the Dodge slave on that just fine, even with the South Bend single disc clutch I have

As for the brakes... I'm using a 12 valve out of a CF7000 Ford cabover truck right now, with the air compressor instead of vacuum pump. I opted for an electric vacuum pump for my brakes and HVAC stuff...and I would strongly discourage that having done so. The vacuum pump I got is from SSBC and is made for "hot rods" that don't make enough vacuum for brakes. Needless to say, it is a one pump chump and does not recover very quickly. I would suggest, if you want to keep the compressor, to look into hydroboost brakes from a late '80s thru '90s F-Superduty. I think you can pick up a "reman" hydrobooster from the parts store for about $300, then have some lines made to loop into the steering pump. Places like Jeff's Bronco Graveyard have hydroboost retrofit kits available for about $850. That is probably the route I am going to go next time. Hope that helps!

 

thanks for the advice! helps me out a lot!

 

Just use the Ford pedals. I went ahead and used the Dodge master and slave cylinder, but you can use the Ford master to the Dodge slave like 93Fummins said.
