Oil pump shaft?

[BillaMustang]

I was talking to my machinist about oil pump shafts and he said to stay away from ARP and Ford Racing hardened shaft's. And to stick with a stocker because the hardened shaft's if they barely twist will snap and a stocker will not. Like as if there to hard?

I'm also running a standard volume pump. So what do you guy's think? It's for my 331..

I've never heard any junk like that. What kind of setup are you using? I put 240,000 miles on a FMS oil pump drive shaft, and lots of users have gotten many miles out of them with no trouble. Let me know.

Yes the stocker will teist like a piece of Licorice, and the hardened shafts will just snap...however I would still put in the hardend shaft since it will take more abuse.

I like the Ford Motorsport shafts they have deeper reliefs then the ARP which can cause some issues on EFI Fords if the dist isn't clearanced. Probe offers a new billet shaft looks nice.

I use the Ford Racing hardened one on my motor, no problems here.

I believe you only need a stronger one if you run a high pressure pump,, at least that's what dss recommended, they sold me the ford racing one....

If you rev high, use a high volume/pressure pump, want peace of mind, or all the above, then get a hardened shaft. Yes, they do snap(done it), but it takes alot more stress to snap a hardened shaft than it does to twizzle a stock one. In fact, after I broke my second FMS shaft on another car, the bottom of the distributor shaft had split too.

If I'm going to have the pan off of an engine, be it stock or modified, I'll put a new hardened shaft it.

Well thats it I wont be using a High volume nor a High pressure.

They said I will only need a standard pump because it's all in the clearances.

cool... the key is "standard pump because of the clearances" IF you bend or twist or break a pump shaft.... your in trouble!! I have used both and all I build with are the hi-vol pumps ( loose is better). If there is pump lock up.. who cares if it twists, bends, or breaks... the trouble is there!! as for the performance shaft being "brittle" and breaking easy.... dont think so.. or why use it??

Just me.......................

Neither am I and I have an ARP shaft.

This is stock:

(edit) there is supposed to be a picture here. I attached it and look at that, nothing.
