I will be happy to take pics of the whole mess. It will take a day or so to get it together.
This is a must for extended periods of operation above 9,000 RPM. The thinking is that the upper gallery is through the dowel tubes and they are threaded thus making for a poor oiling path for the front main.

This is the plate that replaces the oil filter adapter and provides a dash 12 oil pressure in from the pump and filters. A dash 4 to the oil pressure gage. Unseen on the other side is a sender for oil temp. and the hydraulic 45 fitting is the dash 10 line to the front lateral gallery.
The steel tube shows the path from a fitting on the drivers side to the main bearing. A nice straight line.
The brass plug is drilled out and the hole tapped for a dash 10 by boss fitting. An aluminum washer is the only seal.

Here is a front plate modified to oil the front main bearing from a hose from the oil filter stand.

This picture shows the path of oil from the rear iron. This takes out three 90 degree turns with razor sharp corners. The dowel run is left open so the supply plumbing cross section to the front bearing is more than doubled.

easy
ready? cold night+non working air sensor+shifted early in 4rth gear which created much load in the engine=boost spike=Ping=cracked plate/apex seal due to use of Pump Gas instead of Race gas
and yes my A/F's should of been in the low 11's for pump gas
but was running 11.8 A/F-11.9 A/F which seemed very nice on race gas and made alot of power but was border line on pump gas

that AFR will not break an engine. unless you had previously damaged it by running too much timing or a shoddy engine that was ready to go

Any pictures of this setup?
And when should one consider this setup?
And on a side note, usually don't the front stationary gears/front rotor bearings/teeth mess up before their rear counter parts?

This gives you two paths for oil to the front main bearing. Not only are there threads in the dowel run from the rear gallery, there are a number of razor sharp 90 degree turns that reduce oil pressure.
