A most impressive piece of engineering. Do you have pictures of the complete car? They would be interesting to see.

It has the look of a lakes racer about it, it would be great to make it look stock and have some fun with a Porsche or two!

.jpg   DSCN3196.JPG (Size: 120.61 KB / Downloads: 256) Has anyone  changed  cam bearings (bushings)  to needle bearings in 3 main crankcase ??  The ends are fairly simple ,  but the center seems a challenge .. I am working on this now , will know soon if it works ..   I know of the earlier cases with needles , actually the size of rollers , this is different ..   STEVE   Pics of my '37 Opel with turbo and S/U carb , Pauls road cam , Dante head ..
