I don't know, that is for you to decide with your own K5.So are you tell me I need big hp to be happy with mine compred to the duramax.![]()

For me, it would be a ton more fun to drive my K5 If it was a snappy RPM spinning tire burner. It's close right now, smaller rubber, lower gears, and some good heads would REALLY wake up my motor. I've heard that on big cube small blocks, heads can make a huge difference.
