The blocks were drilled for the spider valley fasteners for years prior. Someone could have added it and the roller cam.
More likely, it is an engine from a car. That would explain the intake setup. The F-150 setup is much different.
If someone was knowledgeable enough to install a roller cam & spider in a roller-ready, but not equipped block, they would be experienced enough to install a the compatible distributor, or distributor gear.
