Reverse Flow cooling has recently been used in some High Performance Engines such as the Chevrolet Corvette, and I believe that GM also used it in most of its V8 engines during the 90s.
The Buick RoadMaster from 92 on, used a 235HP variant of the Chevy Corvette 5.7L V8, but it was Throttle Body Injected, rather than Sequential Port Injected. The Collection Series of the RoadMaster, I believe, built for 1996 (last year built), has the Sequential Port Injected V8. All of these V8s were REVERSE FLOW COOLED. GM claimes that by reversing the coolant flow, the engine burned fuel more efficiently than with the conventional coolant flow.
