408 Cam on the way

Looks like right cam wrong spec sheet, per Ken.
I will verify when degreeing.

Ken suggested 2 degree advance, citing potentially too much cylinder pressure with 4 degrees. I’m not sure about finding a chain/gear set to do that. I may see how the pistons sit in the deck then decide.
