What bearings to get my 408?

I had to narrow stock app main bearings for the journal radius.

The second time around I just bought the full groove mains, they are narrower than stock ootb.

When it comes to full groove bearing psi loss.....well full time oiling will do that, as for clearances..thats 2nd to blame, mine are only .0024'ish on the mains and .0017'ish+ on the rods.

They have found less than 10 psi per 1000 rpm to be sufficient, as low 6-7psi per grand even.....however the add psi '@ idle for instance' & 'to an extent' will cool the bearing/journal faster and bring the viscosity back that all oils lose no matter the brand/cost....which is why I always run a 20w50 btw.

there is a line between enough psi to cool/lube and too much viscosity which is creating more heat when having to compress it.

I really hope I dont see lower than 25psi at idle, but it may take a spring in the oil pump to insure that.

just rambling now...
