I just was going to ask you do that. You beat me to it.

I get up pretty early... 😂

It may be of interest to note that the LS3 cam is available with 1 bolt / 12623066 or 3 bolt / 12631811 same specs.

According to my SA Design book, the addition of the LS6 cam ALONE to a stock 5.3L engine was good for 40hp on the dyno!

Awesome! Thank You
