Welcome, Darcane, which track do your parents own, if I may ask? And, since this member's sedan is about the same as your wagon's, start on this page of this thread, to see all he did to fit an LS drivetrain into his Caprice: http://www.stationwagonforums.com/forums/threads/fixing-up-a-71-grand-safari.19936/page-57 it begins with the post where the Caprice is sitting in water.
Alaska Raceway Park near Anchorage, AK. It's an IHRA 1/4 mile drag strip and NASCAR 3/8" mile oval track. Thanks! Lots of detail there for me to hopefully learn from his mistakes. Any idea if the Caprice/Roadmaster wagon fuel tank would bolt into my Electra like that? At LS Fest, they do that swap in two hours.
That's a good question about the tanks, but only one way to find out...grab one from a junkyard, compare them.
