how much timing?
If your car knocks on the spray its probably to late to save it.
Take what ever the max timing you run on motor and take out AT LEAST 6* for a 150 shot.
Timing doesnt make a huge difference in HP you will find more power getting the A/F correct then adding timing.

pull 2 more degrees out and run it and I bet it does not slow down.
Then lean the car out with those 2* still out and run the car and I bet it goes faster.
You guys can be out in left field with a 150 shot and not hurt anything, when you turn up the wick is when you need to know what going on.
