His name is camgrinder here on Pelican. Send him a PM and he should give you an answer.

I have sent camgrinder a pm but no answer.
I really need to find the settings now. With a lobe center of 104, it must be special grinding. Can I use the degree scale to find settings? Or set inlet and exhaust even when overlap? Some who have suggestions? Thanks

Or Google "Dougherty DC20" and a number of Pelican posts come up that have your answer. Tried posting the links yesterday but didn't get them past the moderator!

These were a custom ground set. He has the setting now.

DC20 cams
Just a little late feed back.
Thanks to John Camgrinder for providing the correct specifications. I would set these up at 3.4mm. These cams are more aggressive vs. the 911 E. Fall between the solex and 911 S profiles. 248/236 @ 1mm with .470 / .450 "valve lift. 104 lobe separation angle. I was busy getting the engine done. The car should drive historic hill climb and the engine in the car was 3.2 and not allowed. I thought the car would be slower with 500 cc less a comp. ratio 2 points lower. But no, the little 2.7 is much livelier from 5000 rpm and 20 kg less. The car won 7 hill climbs in 2017 and became champion in Denmark in historical class. ![]()

That is a Fine looking car Daugaard. I'm also really happy with cams John did for me. Great performance and holding up just fine (no pitting etc).
