340 timing need some advice on rufff timing

cranked more timing in seems to be better tab only reads to 10 degrees

im guessing
im at like 25 lol if the increments are spaced the same further from zero u go
then thats how i come up with 25 car is not spark knocking and still starting fine guess ill go try more lol

also when try to launch the car falls on it face i can not seem to get it to torque up like it should for a hole shoot so fig more timing and keep trying to launch the car till it runs good and will still starts
car is starting to pull good when i do down shift and stick it so guess im getting some where
