Any one interested in the oiling mods I did?

You have to increase the dwell time IF the oil timing is off. That’s the band aid. Like full groove mains. You are getting oil to the rods all the time.

If you read that paper that Phreakish posted they discussed putting oil in at TDC. Or shortly after. Pretty interesting.

Again, I use the SBC a my example. They don’t need full groove mains, more dwell time or any of that, because the oil is there, full flow, full pressure at the correct time.

Obviously if the big end of the rods don’t stay round, or they have too much clearance (almost as bad as too little clearance) the pan sucks or some other issue, that system is pretty much bullet proof, even if you oil the mains after the cam the OE stuff did for decades.

I gotcha. Well all I can hope for is that the difference will be minimal. I opened all the rear block passages, so maybe that will reduce the difference. I will look at that rocker timing when the time comes. Thanks for teaching me about that, never looked at that ever before. Do you know if the Norris rockers also have the timing issue?

I LOVE those rockers. The issue isn’t the rocker, it’s where Chrysler put the holes in the shafts.

I have never seen any shafts sold as W2/5 stuff that had the oil holes positioned correctly. They are actually laid out for the T/A offset.

The brand new shafts I have are wrong and need to be corrected. I wrote a long technical papers with drawing and such and Chrysler blew it off.

You can mock yours up and see what you have. I’d bet everything o have that the holes will not only be off left to right (as in the hole is too close to the rocker centerline) by .100 or so and they will be off radially. Especially when the geometry is correct.

I tried grooving the shafts but it never worked. I just blue the shafts, mock it all up and take the adjusters out and go through the feed hole to mark the shafts. Then I drill new holes in the shaft and plug the old holes with lead shot.

You do that and the adjusters will oil to well past 9k with 360 or more on the seat.
