Dropping a motor in- any last tips or advice?

After many delays due to personal and business reasons as well as some competing financial obligations, I'm FINALLY ready to actually put the Magnum into the Dart.

The transmission is bolted up but the exhaust manifolds and accessories are going to be installed after the motor is in the bay...assuming that more clearance= better.

Do you guys agree? Is there anything that is more easily installed before dropping the motor in?

Secondly, the motor mounts are attached to the motor but I didn't torque them down- because it seems like it might be beneficial to be able to move them a bit to get them into the mounting points on the chassis... is that right? If not, how should I proceed?

Thanks in advance for any words of wisdom.
