stock cams.

[nicolas]

been wondering about this for a long long time.

is there a difference between a Type3 and a Type1 cam? some say there is, i don't think so. but i could be wrong.

[nicolas]

up! 

[deano]

I do not recall there is any difference. But I do remember that the way VW measured their cams is different from the way aftermarket cam grinders do. Nowadays, cams are measured at .050 checking clearance, and OEM VW was probably closer to .020 or less.

A simple way to check this out is to look at the part numbers in the VW microfiche.

Stock T3 and T1 cams had same part number, beginning 113 109 ***.

[nicolas]

thanks.

then why is there so many people claiming they have a type3 cam in their engine?

 i was confused after reading it for the umpteenth time, so i had to ask.

[danny gabbard]

Where the cams ground different between type's 1-2-3 ?

[deano]

I think the old wife's tale about Type 3 cams came from the "S" version, which made more horsepower, which came from domed pistons as I recall and nothing to do with the cam.

And yes, Gab-Fab, how many years ago did any cam regrinder care which car it came from? All looked the same to them.

[danny gabbard]

Were they different from the factory?

Anyone ever bothered to check a stock cam @ .050" to see the numbers? I'd be curious...

I remember dailing in a stock cam with Dave Kawell years ago, and they are tiny..... and short..... and don't overlap much... An Engle W100 is radical compared to a stocker.

If I remember correctly, the opening and closing #'s are in Bill Fisher "Hotrod" book

Yes, sir! And a great cam it is. I built a 1641cc from scratch, had Rimco balance every thing, mild dual port heads, that cam, standard size Phoenix header with the hidden muffler in the passenger side fender-well, sawed off exhaust tip, fake pea shooter tips, factory doghouse cooler and shroud, tall K&N filter, reamed out the main jet of a 34 PICT Solex as much as I could, and a Bosch .019 for my Java Green European '66. GREAT engine. Did a wonderful job, serving as my daily driver for several years. Even beat a guy, racing... he had Kadrons on a stock engine with a Bosch .009 and a header. Made my day. Both of our cars were 6v, too.

yes it is! Happiness is often a stock cam.

Intake: 7.5 open, 37 closed lift 0.322     duration 224.5
exhaust: 44.5 open, 4 closed, lift 0.310  duration 228.5

measured at 0.040 valve clearance.


and if i remember correctly Fred, the W100 was first ground from a stock cam. somewhere here on the Lounge there is a story about this. and nice combo on that engine, i plan to build the exact same engine for my type3 but with dual type3 carbs (019 single spring, selfported (cleaned) heads, 1641, cyclone header with a chrome tip in the stock location. actually that engine was build, but the cam was different and i messed it up using old, glazed cylinders... , oh and it will have the original heatersystem, i know you like that as well even if you live in Cali )
thanks for all the help

.019... God, I miss mine. Great distributor for small daily driver engines. That W100 cam thread sounds cool, Nicolas. Thanks for the history on the first grind on that, too. Kinda cool in a way.

Hmm, that's a strange way of putting it. That is a lot different than measuring the actual movement of the dial indicator up the ramp of the cam lobe .040-inch, from zero on the heel.
