You are right, the Q motors have different timing requirements from any other SBC. Don't ask why, we don't know, lol.
Your post is on a thread about the "F" motor, which is different than the Q. Roy posted the proper image for the Q, and you'll see it is different from the F (thanks Roy).
Stranger things have happened than having an automotive guy try to make one run with conventional SBC timing and wiring. The Q motor is a great series. I have access to all the info, some of it is on board a family member's boat. Most of what you will need is already here on the forum.
This would be your first hunting ground for info

To save you some time hunting, here is a link from Forum 350Q expert, Mark Weller (it's the entire manual in PDF form) (thanks Mark)
