I'd try something smaller first. When my 460 was on stock carbs the main was 85-90 depending on exhaust and filter choice. Indeed, I have some 100 mains somewhere that have been only used once...

My 466 is running well on 90's with stock air box and open headers,  may have to adjust when I get some mufflers on there.

90's it is then.i'll start out with them.thanx ,mitch

There's a user here named Jezzem that has a similar setup on his 400F and is quite knowledgeable, perhaps seek him out and ask some questions.
