His Cams were made by Clay Smith, possibly still are. Depending on what you have planned, his 57+ cam might be a good choice.

I think what he is saying that with such a cam, it is considered one is using an FMX or C4 AT on the street. The F/M would not hold up to it and there is no high-stall convertor for a F/M. One would have to use a much later FMX convertor with extensive modifications to retain the F/M.
Not feasible or cost effective (IMO)
