Ive posted it before, but why will a Chevy turn RPM until they bury the tach and not blue a bearing? Because Chevy has the oil TIMING to the rods correct. Chrysler does not. As RPM goes
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?
