My faithfull RRC is running again, though still with a blown headgasket at one cylinder. The engine as such has a ticking noise, but pulls allright.
I've found another high-comp 3,9 engine though, which has been put aside for two years now, according to the seller.
My thoughts were to renew the waterpump, as well as to change camshaft, lifters and chain before I change the engines.
I would like to hear your opinion on camshafts, as there a several options. I know there isn't a direct No.1 choise but several, but I have no experience in what works well with my setup.
RRC 3,9 automatic, never off-roads but occasionally used to pull auto-/horsetrailer. My aim is a mild tune - low-rev torque, and a straight swap without having to replace valvesprings or work the heads.
I found following choises :
JE101 : Have read good about it, but unsure if it's still available?
High Torque from V8tuner : http://www.v8tuner.com/product.php?id=693
Piper Torque Max : Available at RPi?
Real Steel Viper Cyclone or Viper Hurricane
And a question : I've read in earlier posts, that break-in of the new camshaft, with zink-additive designed to the purpose, is essential - but could be dangerous with ZF 4-speed automatic?
Thanks in advance for your advice.
