Where might I be able to buy/borrow/rent a replica LT1 for mocking up an installation into a non-fbody car?

The only one I could find was this: http://www.vanpeltsales.com/FH_web/r...v-sbprices.htm

But that one is like $360... I'm hoping to find something cheaper to buy or rent, or perhaps someone who is really generous and willing to let me borrow one for a couple weeks...

Any help would be great...

Thanks,
