Looking to improve 60 foot

I guess I will mention (although this starts into "significant" changes)....my car used to run 10.8 @ 123 ish with a 1.50 60' (previous engine). A friend of mine rebuilt my 727 when I was in a real jam ( I burned up the trans 1 week before the bracket finals), long story short, whatever he did made the 60' drop to 1.47. After that the car was running 10.7's thanks to the better 60'.

I know this probably doesn't help, but thought I would throw it out there.
