I can't really say I feel a difference. I gave my brother a ride, and he said he could feel more hp throughout the range, but I really don't think I can. Anyway, I definitely dont regret putting them in, I just hope next time I encounter a stock LT1 I can walk em.
Now I've just got those 4.10 gears sitting on my floor, calling for me to let them prove THEIR worth.
