3.9 later intermin Serp Engine project
Posted: Wed Sep 25, 2019 5:48 pm
Continuing on from my previous post....I've gone and got a late 3.9 interim longblock i.e. serp front end and block casting with provision for cross bolting (but not actually cross bolted).
Allegedly the engine has been 'rebuilt' but until it arrives I wont know to what extent. In the meantime I want to start to make a plan for what is to be done with it.
1. Check cylinder liners for slippage & have block pressure tested.
2. Get it drilled and tapped for cross-bolted mains - I'm really hoping I get lucky and it has the correct main caps for this. If not, anyone know if they are available?
3. Get rotating mass balanced.
4. If required hone and new rings
Performance:
Increase CR; Block decked and use tin gaskets
Fast road cam; contenders are Piper 285, V8D Stealth, Kent H214 or H218, Viper Typhoon - Will I need pocketed pistons for valve clearance?
Duplex timing chain
Stage 1 head work
Serpentine ancillaries:-
Just going to be running an alternator and waterpump, so will have to use an idler pulley in the power steering location for belt routing to drive waterpump. Anyone running something like this, if so what did you use?
