Jeep 4.0 in 69 Barracuda

I had a 72 ply duster with a built up slant six and manual brakes (F Disk/R Drum). After building the engine and updating the gear ratio from 2.73 to 3.23 in the axle, I instantly didnt like the brake feel and updated to Vacuum operated Power Brakes. Especially on Western Washington mountain roads.

I will not run manual brakes again.

I am planning on keeping the front disk / rear drum configuration only this time instead of OEM rear drums, I am running larger 1992 Ford 8.8 rear drums from a Ranger.
