Planning out my 70 Challenger here. Its a 6-cyl car originally, so the K-member will have to come out. I have a V8 one and mounts already handy, but i gets to thinkin'...

If i were to shave off the engine mount stuff on my 6-cyl K-member and go with an aluminum engine plate instead, would i be saving or gaining weight? Does the K-member mounting pads + mounts + insulators add up to more than just a plate?

If its about the same i'd just stick with stock and swap K-members, but if there is even 10lbs in there it might be worth going with the plate. I'm assuming there are other benefits to switching to an engine plate as well...???

Weight is going to be a VERY important theme in this build. Light weight and simplicity. Yet i dont have much money for fancy stuff. I'm willing to spend time on the details.
