Are they labeled in units of .00X mm, or are shims available in every .001 mm increment? I am going to guess the former; otherwise, you would need 1,000 shims in your kit just to accommodate a range of 1 mm.
For example, Alfa shims are available in .025 mm increments, so it takes 40 shims to span 1 mm of range. While the dimensions of the shims are labeled to the nearest .001 mm, that doesn't mean you are expected to adjust your valves to the nearest .001 mm. That's why I found the page from the shop manual that ghnl published, giving settings in .0001" units (= .0025 mm) to be kind of funny - that's an order of magnitude greater precision than off-the-shelf shims provide.
Admittedly, this is only amusing in an "engineers' humor" sort of way.
True but Fiat shims weight a lot more. Not an issue on street engines but some Fiat racers with unlimited budgets changed to the Alfa bucket over shim method to reduce valve train weight.
By the way did you know VW paid royalty to Fiat for years to use that system in their Golf engines?
What is the tap/fitting connection size for the low oil pressure sender on a 2L engine block? I plan to check the oil pressure with a mechanical gauge which has a 1/8" npt fitting. I'll need an adaptor to connect it I'm sure.
I am up in Magalia (above Chico, 100 miles north of Sacramento) I could really use a weber capable dyno tuner to sort out an abonormale build with 4 DCOE carbs. It runs very nice at low rpms up to 3500, has a vibration/stutter at around 3800 rpm to 4000 then smooths out to 5000. I am not...
Can anyone help me with identifying these Venolia pistons.
They are stamped inside Venolia and RT>. They are 78.9 mm across the shirts so are for a 79mm bore. The dome rises 20.6 mm above the deck line with large valve pockets. 3 rings

I have a Ar 118.284s camshaft here.
I suspect it to be a Colombo bariani, but cannot find any data on it.
Measurement tells me the lift is 11,3mm
I have another camshaft, looks like a c&b too, but no markings. Measures a 10,1mm.
