Roller rocker arms for 230

[chimesickle]

Hello, I tried the search engine first, couldnt find anything. Just curious if it was possible to use roller rocker arms on these stock engines? I hate the way they wear down the cams.

Never heard of any rocker arm off another motor that interchanges and there certainly is no roller made just for the odd 230 ohc motor...especially at .375 lift...

OK, thanks. I guess I was dreaming. I appreciate the rapid response, though.

Just happened to be online...

FWIW you might be suprised what a hungry machinist will make for you if you've got the specs or a decent drawing. Lots of shop guys out there have CNC's at home, and once you make one, multiples are easypeasy (and therefore cheaper)

I have a CNC mill back home... When I'm back, if you want to send me a g-code file that makes rocker arms (or, at least, really detailed drawings, as I'm not pulling my engine apart), and suitable metal to make them from, I'll do the rest free just for the practice.

Of course, being a small tabletop mill, the accuracy is a bit lower than I'd like, and it'll take a week each if you want them made out of steel!

Thanks for responding to my question, and the offer. I think it might not be worth the effort and expense. The distance from California and New York is just one obstacle. I do not know what a G code file is. I have been too busy making a plow frame, and brackets for hydraulics. Since it runs, I might as well make it plow snow.

I hear you can find roller rockers for an SBC just about anywhere. Hint, hint- wink, wink.

Yes, you are right.
But I think the military motor is cool. It is designed to be waterproof, and was engineered for the vehicle. I still have 24 volts, and am trying to keep the exterior stock looking. I have no need to change the motor yet. Just bummed by the rocker arms rubbing on the cam. An ingredient in oil that prevented wear was eliminated recently. Now antique vehicle owners have to buy an additive.
I was hoping that something could be substituted. Yes, I have been adding the Pennzoil synthetic marine 2 stroke oil to my fuel.

It's the zinc that's missing from modern motor oil. All my motors are flat tappet lifters- lost a lifter and cam lobe on my 454- resulting in a broken valve spring and it's metal getting down into the main bearings. Motor had 25K on it. I add Lucas oil zinc additive with every oil change now.
