A motor building friend of my asked me this question and I thought I'd pass it on:



I am working on a 1957 Ford 292 engine out of a 1959 all mahogany Chris-Craft. It's a reverse rotation engine and it needs another cam. While doing your research for your engine did you find anyone who might be able to weld up and regrind a reverse rotation cam?

I believe the marine engines used standard cams and had a gear drive instead of a chain.

There's a LOT of reverse rotation engines out there. But they're mainly GM engines. Mercruiser and Volvo Penta abandoned Ford Marine back in the 90's (or Ford abandoned marine engines!!)



Having said that, Any specialty cam grinder should be able to make you a reverse rotation cam but it wouldn't be cheap.



You'd also need to do something with the circulation pump wouldn't you? (although I think some of the Y marine engines didn't use a circulation pump....and just used a "crossover")

I dont know if youare aware but there is a site for the Ford 312 "Interceptor" motor.You would likely get some information from them about where to get special cams etc.I just bought a pair of chrome valve covers off one of those motors.Interesting thing is there is an oil fill cap on one because the intake has no oil fill tube.Bought em because they are the same quality as the regular steel covers and are much better quality than the offshore stuff.

  

I bought a used marine block a few years back, and that's exactly how it was done. Any Y block cam (with the correct dist gear) will work. Ditto for the distributor, which in this case was a Mallory single point, and the oil pump.
