1968 L88 Corvette

[big gear head]

I have an intake manifold from an early '68 L88 Corvette. I'd like to find the car that it belongs to. Is there any way to find information on who has these cars? I think I read somewhere that there were only about 20 of these made in '68, but then I also read that there were about 40. It's also possible that the car that this came off of is at the bottom of Green river. I heard stories when I was a teenager about a Corvette that was stolen from up north, brought down here, stripped and pushed off into Green river just outside of town. The guy that had this intake manifold use to race a V drive boat with a L88 in it, so this could have been where the engine came from. The casting number on this intake is 3919851 and the date is 9-20-67.
