Can anyone tell me if I should go with a #2 or #3 cam setting for this Erson cam. My engine is a 402BBC

My vote is #2. I run a solid flat tappet that is pretty aggressive & I'm using #3.

Yeah, I'd start with 2 and take a log to see what the AFR learn looks like.

Thanks for the help guys #2 has been what I`ve been running, I also finally got thru to Erson on the phone and their tech said that cam in a 402 should be set as a #2 in the fitech.
