Std camshaft Spec

Post by Mimic » Tue Mar 12, 2019 12:51 pm

Hi,

I am going to rebuilt my engine and I wonder some question about std camshaft spec.
My first approximative measurement give me +6,1/ 6,0 mm for cam inlet lift
My manual annouce +6.45 mm for std camshaft
On Car clinic website wrote +6.26mm for std camshaft (if you take 1.475 for rocker ratio)

Where is the error? It's not the first time my manual give bad spec (main journal diameter for example) . Does Problem is known?

In case of a worn camshaft , could I easily regrind this to standard or mild/fast road camshaft spec ? (I've any experience in this )

Thanks

Yes, I believe the car is an Se5. However, in relation to the engine, see this thread

So the manual isn't wrong - you have the wrong manual :D

I have spent many years trying to get a SAMCOR manual for the Essex from SA (for the EFi Essex) without success.

Probably ! But heads seem to be original (but very worn) . Carb is an early Weber DFAV 40, early oil sump , oil gauge in front cover etc
Just cylinder block seems swapped ..but I've no idea for camshaft, even if I presume they kept the old one

Camshafts are interchangeable, it`s only the Cologne that used Two different sizes.

Which manual are you using? By oil gauge, do you mean dipstick position? Does the block have a hole in the side for a dipstick? Do you have oval port heads, or D port? Can you post a picture of your rocker covers or the inlet manifold, showing the bolt holes (they’re different on the SA engine)

Rocker ratio is difficult to be exact with because it’s rounded down from imperial measurements, then converted to metric and rounded down again - but the Reliant manual gives cam lobe lift and valve lift.
