I have many Ideas for different projects and most of them would use fairly high dollar engine internals. So now my question, Are there any good websites that sell exotic internals? I am looking for something more than Sumitt and jegs offer. Possibly 1.880 in. rod journal cranks and stuff like that I am very curious about what it would cost to acquire the internals of an engine that many builders would charge well into five digits for.

One more question, does someone have a link to a site that has good engine building secrets? Theories? etc etc.

Thank you for any help and I hope this isnt out of place in this forum I just assumed the high tech forum would be the place to ask about exotic parts.
