I can't talk to the car itself but I can on a Keith Craft engine. If it's a 427 with a 351 w block then you may get a rear main
oil leak. If you look at their warranty they don't cover that. I've got a KC 408 and have a very small leak in the rear main and had to fix a larger one up front (again not covered by warranty) My engine has about 3000 miles on it now and other than the
oil leaks it's a badass engine.
