1st if you look at the hot temp viscosity your looking at 3.8 which is almost a 40weight oil. Both redline 5-30 and M1 0-40 are 3.8.Both M1 and amsoil 5-30's will be thinner then both of these products and not as much of " The Good Stuff ". A heavy 30weight is very suitable for this engine and any LS based engine.
Red Line 5-30 has more then enough ZDDP roughly 1300, but it's also loaded with moly aswell. Oil temps approaching the numbers you posted is extremely high. I usually see about 220 in my LS7. You may consider an aftermarket cooler .
Pablo Im not steering him away from Amsoil. I don't usually mention the product as I don't feel it's better then Redline and for me Redline is less expensive and easier to get. Like I stated my engine alone cost 21k I know what I trust in my mill. Many of my customers are dirt racers and duners I personally don't know anyone that uses Amsoil in their race cars or very expensive toys. If the OP chooses Amsoil then more power to him. Im sure it will work for what he does
