Look, obviously, I have some concerns about the HOT MAX PSI.
This is my question, why is it that you and a few others need to be critical?
Yes, I am posting again about the same engine, BUT perhaps I have a reason? Perhaps no one has yet given my the definitive expert answer I am seeking?
I am asking some builders and was hoping someone on here could share their knowledge on the subject.
Obviously, you cannot. Thanks for your helpful response thou.
Oh, in that case go back and read Mitch's and 427Z06 posts from your old thread. Get that 30 weight oil as soon as you can and at the least put in a 15w40 diesel oil (Chevron Delo's latest brew is hot stuff) while you make up your mind. Track the pressure while oil is hot at 2k, 3k, 4k, and 5k rpm. Old rule of thumb is you want 10 psi for every 1000 rpm (so 50 psi at 5000 rpm, etc) but with your engine I don't know if that still applies.
If this car does more than just race (street driving too), don't use a race oil since it needs the detergents and other additives used in street oils and less so in race oils. So out of those 3 oils, I'd go with GTX for sure and lately, GTX seems to be a great conventional oil.
When the new diesel spec (API CJ) comes out in the fall, use a 15w40 that meets that IF that viscosity gives you good oil pressure. Those oils are supposedly going to kick booty and will also be great for gas engines due to less ash than current diesel oils.

Good choice.
