I know some of you are engineers.... - Page 2 - GM Forum - Buick, Cadillac, Chev, Olds, GMC & Pontiac chat


Performance, Brainstorming & Tuning Talk about modifications, or anything else associated with performance enhancements. Have a new idea for performance/reliability? Post it here. No idea is stupid! (please use Detailing and Appearance for cosmetic ideas)

It'* also going to be hard to use the transmission'* weight because you don't know where the center of gravity is.
.5" higher and 7" back from the CV.

The center of the tranny'* weight is about 2" back from the block mounting face and 15" from the front mount face. it'* nice to have chains and a hoist.

The more i think about this, the more i realize that you need finite element analysis to really tackle this. The only program i'm really familiar with is ANSYS (hp) and i can only access it at school. I know Bill is pretty good at another FE program. Maybe you can convince him to tackle it when he gets back from my home state?

I would assume the force would be upwards paralell to the upper face of the mount, with maybe a little bit to the right because the motor wants to go up and back.

If the CV has 500ft. lbs. applied to it, how much lifting force is applied to the front mount and at what angle? Also note that the mounting face of the front mount is one inch higher that the centerline of the CV and rear mount. I assume the wet weight of 375lbs for the drivetrain may apply.

the rear mount would see 857.53 lbs. of downward force,
The front mount would see 333.33 lbs. of upward force?

Sure, Thanks.
