i think bench racers don't know squat about building these motors. i ran 65 and 178 stacked with 550 looped rail tuned and ran 11's and was in full street trim and drove the car on the street with zero issues.

having said that if you want to run 11's all thats needed is d/r slicks, a 181 pulley a single cai and a competent tune. 11's all day
