rocker arm oiling HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Saying all that, what I'm saying is decades of testing has shown that you need full pressure, full flow oil to the rods when the piston is about 70* ATDC. That number varies a bit depending on Rod ratio, but that's it.

If you measure a Chevy that's where it is. Look at a Chrysler. It gets the oil there too early. That's why running full groove bearings help. It puts oil to the rods all the time. It won't make a crank live at 8500, but it helps.[/QUOTE)

My question is.
If I grove the main saddles on #2,3and4 around to 70 degrees on the drivers side(left side) and drill thru the bearing at the 70degree point. Would this help keep the rod bearings from going away at 9000?

To me the real question to be asked is whether you think full groove bearings are a disadvantage as far as adequate bearing surface.
The Chev method of grooving the saddle still gets less volume to the rods than a full grooved bearing, but the Chev does not use a full grooved bearing. When I talked recently with Mahler clevite they are against full grooved bearings. But Chrysler still recommends there use. Go figure. Converting to full time rocker oiling by abandoning the cam timed oil passages certainly cannot hurt crank bearing oiling.
IMHO. My last build failed 2 and 4 main because I screwed up that restriction, so you certainly cannot say that the rocker feed restriction has no effect on the crank bearings. Why not make all the crank and rod bearings all oil the same way by getting rid of that circuit altogether.
