You are having the same problem that I was when i was N/A. I also have the Darts 2.02 and I was DOG SLOW without my blower. I would run mid 13's but when I ran with a blower I droped down to low 12's -High 11's. WIth only a cam change and blower addition.
My setup now is
Dart heads (2.02), Edelbrock Performer intake,
crane RR, Blower Cam, 36lb Injectors, 80mm Mass, 65 TB
Shorty headers, Off Road, and Dynomax 2.5 Cat back
AOD, 3:73. Stock suspension and 3225 with Driver
T-Trim supercharger
Right now I run 6.98 @100.33 in the 1/8 mile with a 1.64 60ft
with my old Powerdyne 7.57@ 92.2
SOoooo, the Darts are very capable of producing power but you HAVE to have a blower to make them work on a 306 ci motor.
