420a Turbo torque specifications.

[defeat54]

Friend is about to build my 420a motor with forged internals. Eagle Rods, Wiseco Pistons, Polished Factory Forged Crank, Acl Race bearings, Arp head studs & main studs, Supertech Valves, Springs & Retainers And BC stage 1 camshafts.

If you have any torque specifications for any part of the engine, the help would be greatly appreciated.

Were did you find Brian Crower cams for the 420a never seen or head of them or do you mean Crower cams big difference. As for the specs they should be the same as stock tq specs look in a Chiltons or Haynes manual you should be able to find all the specs you need their.

For the arp fasteners (rods, mains and head bolts) use arp's specs with arp lube. For everything else, use the oem specs.
