need 3/10th

A stick car will have a launch rpm window where it works the best. This is difficult to say here what that would be. (Engines cam and power torque level at launch all have to jive together at launch. Of course...)
Also as stated above, the cam trace will have to be adjusted. One side more than the other.
This has to be experimented by you. I think your set up is a good start and it just has to be played with.

Get it going straight first. You’re on your way!
