The card says 283/283 seat timing, 255/255 at .050 with .620/.620 lift using 1.6 rockers on a 105 LSA installed at 105 (so straight up) and a .014/.016 hot lash.
After talking with Jim at Racer Brown once I had it up and running, he said if I want the seat timing at .020 lift like Comp and some others calculate it, it's actually 280/280 seat to seat.
That's why I say it is 280/280 seat timing because most companies use the .020 lift number and not the lash number.
