illustrated engine view

Anyone out there know a site that I can go too. That shows an illustrated view of my (81) 633csi engine. Before I start playing with my engine I would like to see the lay of the land. any help will be appreciated. Thanks. Bgonz.

Do you want internal or external layout diagrams?? If it is external I would take pics and lable everything. But if you find a vacuum diagram let me know I have 2 extra vacuum hoses from my intake and cant locate where they belong.
