LOL, yea, mild in terms of a twin turbo. Maybe just 10 lbs of boost, 750 HP, fairly mild mannered idle and lots of torque as low as 2500 RPM.
I never knew they had a crate engine based on that block. I have one of there first iron block 427 crates. Valve guides and seals keep the headers well lubed, but
oil is cheaper than the solution. I'll fix it one day.
