    Of course the Indy engine was very good at what it was designed for, which was not F1.
    Conversely, the Ford Indy engine had some marked success in dirt track racing. The trick was to swap sides on the cylinder heads so the header pipes wouldn't be blowing directly into the driver's face. Here's Big Al's version:

    Very interesting. I was unaware the front engined dirt cars used the DOHC Indy motor. Am I correct that this would be a very expensive motor for this class of racing. I thought they simply used tuned push rod engines as in many other racing applications,

    The front layout calls for a completely different exhaust system. Can you explain a bit further on the exhaust layout changes.

    It was expensive but they were also running Offys at the time which weren't cheap either. As I understand it, they just put the left cylinder head on the right bank and vice versa so the exhaust ports were on the down side. I imagine they swapped pistons as well since I doubt that they were symmetrical. I actually saw one race in a Sprint Car on the half mile track at Knoxville, IL with Aldo Andretti (Mario's twin brother) driving. I think most of the front engine development happened after A.J. Foyt took over production of the powerplant.

    Looking at references I note that USAC dropped dirt track races from their championship in 1971. There were many races still run by other sanctioning bodies, but would these tend to feature less sophisticated Ford motors, or did the Indy engines remain popular for some years?

    I don't know how long they continued to run them in what USAC called Silver Crown cars. About all the cars that run now use the small block Chevy. I don't know if overhead cam engines are even allowed now.

    Here's Big Al Unser on his way to winning the 1975 Springfield 100 Silver Crown race in a car with a Ford Indy engine.

    The first driver constructor to race his own car in a WC F1 event, was Jack Brabham, Brabham-Climax, 1962 German GP. The last would be Emerson Fittipaldi, Fittipaldi-Ford 1980 US GP, Watkins Glen. Other constructors such as Stewart and Prost did not race their cars.
    In all probability Fittipaldi will remain the last one.
