Charlie,
as you can see in the photo I used a laser light level to find the distance, but as you probably know the line gets somewhat thick the father you get from the source. SO you can add or subtract a 16 th. I got 4" 15/16. Ed Klepis probably has that figure in his notebook. Let me know what other numbers you come up with.

I hate that you went to that much trouble, but I really appreciate it.
When I called Van's yesterday, their tech guy basically said that they don't have that dimension; they just put the motor up there 'where it looked about right' & built the mount to it. He scaled it off an RV-6 drawing & came up with 4 3/8".
Apparently, this is basically one of those 'get it in the general area' kind of situations.
Are you using the stock Van's cowl? What's your firewall-to-prop flange distance?
Thanks,
Charlie
