460 oil system mods
I have read a few articles about the oil system woes of the 460. One (which I can no longer find) went so far as to drill additional holes and add tubing to the rear of the block for extra oil for the main bearings?
Some suggest a high psi oil pump but caution to use a race filter and be careful on cold start ups. I would be for a high volume, but not high psi oil pump.
Any links or advice would be helpfull. My 460 will have a mild build and not be used for racing.
Thanks.

your mistaking 460s with 335 series engines (351c, 351m/400)
Even high horsepower engines survive quite well with the oil systme the way it is. HV oil pump, drill one hole to spray oil on the dist gear was all i did in a D9tE block making 900+hp and shifting at 7600 rpm. If it will survive that for several years (still running and it's over 6yrs old now) then a street motor won't have any issues.
The extra lines at the back of the block are for oil return from the heads. In high rpm long duration stuff the HV pumps can empty the pan and pump it to the top of the motor. But once again no real need on a street motor

I had one of the old Ford guys here where I live tell me to help with the oiling on the 385 engine, to put a t fitting below the oil pressure seeding unit and run a extrenal oil line to the pug that in just above the oil filter. Helps with the oil pressure in the back of the engine.

IF you really need to do something you can bush the lifter bores on the drivers side (you can do it on both if you want)
