    Lightbulb 427 Windsor stroker?

    I just got my Atomic setup to control timing and I must say that I'm impressed so far. My current timing curve is as follows. Total timing is 34°. Starts at 1100 RPM to full timing at 2500 RPM. 10° on the vacuum advance set to ported.
    The previous setup was MSD 8584 with mechanical set with a 28° bushing and silver springs and 12° of initial timing. With the Atomic controlling the timing as described I noticed an immediate increase in throttle response and power coming off of idle. What I did notice was it seemed a little flat and lazy when going to wide open throttle at around 60 MPH. My Thunderbird cruises around 1950 RPM at 60 and when it downshifts it starts pulling around 2700 and up. Car is a 1964 Thunderbird with an AOD behind the 427 and 3.50:1 rear gears. Should I add a little more total timing a few degrees, or raise the total timing RPM or both? I was thinking going to 38° total and 2800 on the RPM. Thoughts? Suggestions? Thanks, Ed
