My favorite Porsche engine, the cam gearing reminds me of my days racing a Ducati Diana, spent a lot of time at Dan’s Cycles, building the motor.
I thought someone might enjoy. https://www.enginebuildermag.com/2026/01/2-...3914G1587689G5W |

One of my customers has a couple of them. He told me he purchased them back in the ‘70s for $5k each. Also two speedsters for $300 each and a real RSR for peanuts. If they not we could go back in time….

But even with all that he can't get over the Spyder he sold in 1979, which he claims is the reason he won't sell anything now. |

The RSR that he bought after it got crashed is RSR #1, won the Canadian Cup, Harry Biztek driving, if I recall. I think it was this car. I was at his old place in Philly, three Speedsters under water bed covers in his backyard, that had been there since the 70's, rust holes the size of your fist. He said he was going to restore them, when, I asked.... Attached thumbnail(s)
