That is a big change. Not sure what your ET is but if the car is very fast at all then that is a bunch of horsepower that you picked up.
8.70@154 with 35 degrees timing 8.67@157 with 32 degrees
60 foot is a little off @32 degrees. 1.23 60 foot is 1.18 @ 35 degrees
So it wants timing to get the car moving and retard after. Get a high speed retard. You can probably add another 2-3 degrees at the hit and then pull the timing back out .
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
