Re: 479whp ~ 427 ft/lbs on OEM Longblock!
It should be good. My wifes 1G puts down 384awhp on the DD with a factory mitsu longblock with the metal Mistu headgasket, HKS 272s, 50-trim@26psi, 1G MAS. The turbo is just about shot on it, so I want to goto an SC61 and wasn't too worried about the motor taking it. Nash's motor went through hell and held up for a while.
