Hi all,
Researching the replacement of cam, lifters, pushrods, rocker shafts and timing gear.
had a good read of RPI's site and dedided to go for it at 160k kms and no apparent noises yet.
My questions are:
* Is the Piper extra torque cam shaft more durable than oem?
* Is it always necessary to replace the rocker shafts, and also the rockers?
I'll take a little more torque from the Piper, but I'm really intersted in durability.
All comments welcome.
