'Blackfish' Car -- RACE ON AT TALLADEGA ... Thanks to 'Simpsons' Creator

Former NASCAR driver Leilani Munter WILL be taking her "Blackfish" car to Talladega, TMZ has learned -- all thanks to an incredibly generous donation from "Simpsons" co-creator Sam Simon.As we reported, Leilani had desperately been trying to raise money to pay for the $115,000 fee to enter the car for a big race at an ARCA event at Talladega Superspeedway on May 3rd. As of our last story, she had raised only $7,500.But that all changed last week -- Leilani appeared on Simon's radio show to talk about her car and orca-related activism ... and Simon was so moved, Leilani tells us, he donated the balance of her entrance fee immediately after the show ... $107,500.We're told Simon visited Taiji in February (the place where "The Cove" was shot) and has become an outspoken advocate for the humane treatment of orcas. Leilani tells us, she plans to win the race on behalf of orcas around the world suffering in captivity.Sam -- who has terminal colon cancer -- has vowed to give away his fortune before he dies ... specifically toward animal rights and feeding the hungry. As if giving the world "The Simpsons" wasn't enough.
