I had a 14.5:1 Piston, DASA mild porting, and Carb punched out to 41.5 mm. The combo would pull from bottom to the top and never yanked your arms out so it was easy to ride. I'd call it deceiving speed.
Right now that combo is on the shelf for a Duncan 470 kit, but they feel to me very similar.

The Web cam is a great cam. I'm just trying different combo's. While running this combo I could pull holeshots in worcs in the 30B class. I still pull holeshots in 40B with the Duncan against a KTM 570.
The web cam seems to like compression, just check piston to valve clearance

I have used that cam many times. Works pretty good. I ran it with custom pistons " highest comp posible" i had custom made. ran it with 37mm and 31mm valves with my custom valve job. Its a low lift cam with lota duration. so dont get crazy on porting. Pulled many holeshots at ATVA Nationals in B class and A class if you wouls like to see pictures of them i can send them too you.
