Standing beside the engine looking directly down at the top of the distributor you should be able to easily see a flat machined pad on the block just toward the firewall from the hole the distributor passes through. The numbers stamped into that pad will tell you all you really need to know. If that pad is not there you probably have a replacement engine or some other oddity.
