Surgeing after timing adjustment?

36 total sounds right but you obviously went in the right direction if you gained that much at the track. are you running vacuum advance at all? from what I have seen most open chamber heads will like a little more total timing while close chambers a bit less. for comparison my 318 has 302 heads, about 9.5 comp., and the small voodoo cam with about the same for vacuum and i run it with 14 initial and 34 total. seems odd though to have 10 initial and kickback. is the balancer new or is it one you got with the motor?
