Not stepping out of line at all. It's a matter of personal preference and taste. It is less common, and it does echo the hood you're mentioning, I just don't think it flows with the rest of the truck.No? I don’t mean to step out of line, but I like it. Seems more unique than the 2” cowl, while still giving a nod to that factory flat front line on the 70s C10s.
It's your truck, if you like it, make it happen!
