XE 268 cam

AJs Quick guide to selecting an initial timing number;
Basic is 12*
add; 1*per5*of cam timing larger than 220@050, and, -1*per 5* under 220@050
So basic plus;
a 220 cam needs (220 -220)/5 = plus 0*, So 12*, and
a 250*cam needs (250-220)/5 = plus 6*, So 18*, and
a 200* wants (200-220)/5 = minus 4*, So 8*
This will get your T-port sync pretty close. Fine-tune from there
