The cams are all dimensionally the same in the 201/226 engines.
The earlier engines up through some of the d17's had 11 tooth oil pump drive gear, this mates with the 7 tooth oil pump gear. The late engines have 14 teeth on the camshaft oil pump gear, this mates with a 9 tooth oil pump gear.
Earlier engines had a bolt on drive (timing) gear, late ones have a keyed on press fit gear. There are 11 tooth oil pump gear cams also with the press fit timing gear, I think that started towards the later wd45's.
Just be sure the oil pump drive and driven gear are compatible as above, do not use otherwise it will wreck the cam.

I have a cam here that came from a 201 engine, bolt on timing gear, 11 tooth oil pump gear. The shaft is copper colored between the lobes. It's a steel can, not cast but made from a billet. Its got a factory part number stamped in it. I've never seen another one.

copper was a flash plate to keep carbon out of selected areas during carburizing, so that no hardening would occur there, common on carburized steel parts before induction hardening became widespread.

so, if my 1950 wd has a 11 tooth cam and the wd 45 cam i am going to have ground has 11 teeth it will work. the timing gear either bolt on or press fit will work with the cam correct? thanks, Dan

WD and WD45 engines are W engines, and have cam gears that bolt on ,
the later G 226 engines with full pressure engines have the pressed gears . Your original question was referring to the W series of engines I assume, you never mentioned D17 engines. I understand a few of the earliest D17's had W engines, but I have never seen one. W and G engines share a few parts but are easy to differentiate externally , easiest is to look at the oil lines to and from the oil filter G226 lines are much bigger to handle more flow, and the blocks have ribs cast into them to beef them up.

But wouldn't a early G226 cam fit a W engine? up until the teeth count change?

Yes, it will fit. Timing gears are the same tooth count, pattern. Some have 3 bolts, some are press fit and keyed. It won't matter as long as you have a timing gear that fits your cam. The only thing you need to keep a close eye on is the oil pump drive mesh gears.
You could put a late cam in an early engine, change the oil pump drive gear and be fine. The pump would actually spin faster.
Just make sure you have the proper relationship on the oil lump and cam gear.
The very late w series engines had press on timing gear on the cam. All the earlier had bolt on gears. You have to get to the later engines to find 14/tooth count cam oil lump drive gears, all these have press on timing gears.

All D-17 had the 3'' crank even the vary early ones. But there were some earlier D-17 that had oil system like the WD-45s did.

Late WD-45's had the pressed on cam drive gear just like all D-17's did. One more time......there were zero D-17 gassers produced with a "W-226" engine....none. D-17's were always the newer "G-226" which had the 3 inch diameter main brgs and the same oiling system as a WD-45.
