Dude, don't ruin your ride with that motor! I will do you a favor and swap you my 360 so you don't mess up your truck! Get ready to rummmmmmmmmmbbbbbblllllee! Looks like a very nice build.....
Yetiman it's very tempting to take you up on that offer but I'm see how this 390 will run first, it prolly but just a dog...haha, I'm just kiddin, I can't wait to see the difference in power between the old 360 to what I got now.
Understand break in procedure for this type of engine is start it ASAP, then run it at 2000 rmp for 20 minutes using SAE 30 "break in oil" ,high in ZNDP(zinc) ,then change out the oil with favorite brand and weight that is high in Zinc additive.
I got some sae 30 valvoline in it right now with the edelbrock zinc additive ima start it this weekend and I prolly ain't gonna change it right off machinist said run it around 300 miles then change it then regular oil changes after that.
