Has anyone made a small block engine dolly??

Depending on what kind school you go to, I would take an empty block and oil pan into class and use it for a template.

The ones I have was made from 1" square tubing and has a tab on each side that bolts to the bottom bell housing bolts and a tube up front that sets between the motor mount tabs on the block. It was cheap but once it is bolted to the engine it work real well and is very sturdy.
