383 flat spot
My 383 now and then will develope a flat spot just as you go to take off.
it always does it down low from idle as you accelerate slowly you can feel it and if i dont feather it it will stall.
Most of the time its fine.
It has a brand new 650 mighty demon fitted .
Any ideas

Or it could be a squirter size problem.

Good point about warming up. Does it do it when you first drive away? Carbs will do that, people who are used to FI don't expect it.
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
