I have the following spec of engine (work done by previous owner):
- P54 Block
- N42 head
- Reground crank
- All new timing gear
- Lightened and balance flywheel
- Flat top pistons
- Electronic ignition
- SU carbies
- New valves with heavy duty springs
- Oversize lash pads (whatever that is?)
- 72 degree cam
- Head machined true
- Electric fuel pump
Sounds impressive I thought, my son's standard L26 eats it! Plus am told it was fitted with triples and did not perform any better.
I am now wondering if there is a basic set up issue with the engine as it was not done by a Datsun specialist.
From my searching on the forum I have found (thanks to 600Z):
“Another thing you could consider which some people don't seem to do too much with is check your cam timing. Slightly advanced will give you better top end power while slightly retarded will give you better low down torque. This is done by checking the lift of your intake and exhaust valves on the role of the cam.”
I was given the below cam sprocket which is adjustable and was think about fitting it I would like some advice:
- How do I know if this sprocket is suitable?
- Does anyone have a scale template for the timing chain wedge tool?
- What is the trick for setting the valve timing (600Z did give a good insight) just wondering if there is a link I missed that has more detail?
