Humm...........I built my 6 bolt with everything..........4g64 crank, wiesco stroker pistons (86mm and 2.3), eagle rods, BC 280 cams, 1.1mm cometic head gasket, deleted balance shafts, ARP stud kit, JM inlet manifiold, EL ford throttle body, air to water intercooler, ramhorn exhaust manifold, 60mm external wastegate, 800cc precision injectors and Garrett T72 turbo...........only made 408 HP on the dyno at 18 psi with a Wolf 3D V4...........
Total cost.........$8000 when the aussie dollar was good.
Can't see where I have gone wrong............surely your internals aren't standard at 450HP?
