motor plate question

Nick, if this isnt the correct catagory please move this thread for me.


If you run a front plate must you also use a mid plate or is it not necessary? The C6 and Np205 are both soft mounted and this truck does see some street time.

If I have to run both plates is there a way to make a TC that was not originally set up for a mid plate work?


Im starting to look in to winter project and I think a motor plate is pretty high on the priority list. Does anyone have pics, or even better a template, of one installed in a 79 F250 4wd?

If youre doing some serious off roading i would put a mid plate in , you also need engine limiters to keep it from moving back and forth under acceleration and braking.

Why stop with the job 1/2 done. If your going to expend the time/effort of installing a front plate, why not finish the job & install the mid plate as well.

ok, so how does this work with the torque converter since its not set up to be run with one?

Depending on who made the converter, sometimes it will work with no mods if a thin (.090" to .120") steel mid plate is used. Sometimes the center pilot will still engage the crank enough, but the converter mounting pads/brackets won't reach the flywheel & will need some washers as shims. And sometimes the pilot doesn't engage enough. Just depends on how the converter was made.

A thicker aluminum mid plate (.250") will need either the old converter modified for the thicker mid plate (longer pilot & moved/spaced mounting pads/brackets) or a new converter built/spaced for the thicker plate.

Thanks Dave.

depending on where you want the weight in it, you dont have to run a mid, very seldome we do both ,but only in full chassies we always install one

the truck is 6000lbs so a few extra wouldnt hurt. Ill have to do some checking in to having my converter changed up.


Thanks guys.
