I am thinking about buying an older FSV to run in vintage events and wondered how difficult it is to take care of the engine and transmission compared to some of the other formulas. I remember back in the 80's it seems like at lot of the water coooled engines were blown to peices, so I am a little leary of them. Also, I would not be interested in the earlier non-wing cars. Also, I have many questions about air cooled vs. water cooled as far as up-keep and realiability is concerned. The prices vary quite a bit, but for vintage I thought it would be a good choice. Thanks in advance for your help and input.
