Avg 1/4 mile time gain with cam swap

so what you guys are saying that 4.10's show a considerable amount of ET drop? I have 3.42's running 13.40 at 101 on a 2 second sixty foot with stickies.. whats the usual gain with 4.10's? Would i lose trap speed?

That depends on the truck, but generally going from 3.42s to 4.10s will net awesome gains especially in the seat of the pants range.

To the OP you need to drop some weight, add More stall, stickier tires, and some 4.30s.
