I think 38 deg. is a little high. If you have really good heads, the timing could be lower to reach optimum HP and TQ. I know from experience that in a cobra you will not hear detonation or pinging. In a well built race engine 32 -34 deg. is usually enough. As the head quality moves down the continum, the timing will need to be bumped up. Timing can be very hard on an engine and I only picked up a little more power bumping the timng. I also run a locked out dizzy all the time. It is set at 32 deg. That is where I make the most power.
