Reply to "Dart 427 oiling system advice"

Thanks for the reply George.
The Dart block does have priority oiling to the mains, likely the same as the Windsor?
As I’m running the engine as a wet sump & the oil pump feeds the main gallery from the front I have blanked off the front feed to the tappet gallery.
So the oil first runs the length of the engine heading to the rear feeding the mains first along the way.
The restrictor I have installed in the rear where the oil will pass through & up to feed the tappets.
Not sure how you gain access to the cam oil feed, under the main caps/crank bearings perhaps?
All of the oil restrictor kits I have seen available include a bunch of plugs like 5/16” threads that don’t fit the Dart block which is 1/8” NPT.
So I figured they were not suited to this Dart block & designed for something else.
I made a restrictor by drilling an Earls 1/8” NPT plug with a No.3 centre drill which is .130” & the centre drill gives a nice 60 degree chamfer lead into the hole.

I’m running a Comp Cams roller cam & Comp Cams roller tappets.

Regards,
Tony.
