It sounds like your rings are still good, but I'm not sure how long your rods and or your rod bearings will hold up to 400 hp + of punishment. 145k is alot of miles, but who knows. If you tune it correctly and don't knock too much it MIGHT be reliable, but you should seriously consider building up a stronger block in the meantime, because that 145k stocker isn't going to last forever with that type of power going through it. I'd say start at 10psi and then work your way up (see what type of knock you get). You also need to UPGRADE your injectors, unless you plan on not running past 10 psi with that 57 trim (you can max out 550s on an EVO16G) or maybe upgrade your fuel pressure regulator to an adjustable one.
