Any one interested in the oiling mods I did?
I have just been reading this thread and thought I would add a few comments I do agree with most of these mods but there are a few others that can be done . over here in oz our cars came factory with remote oil filter setups to fit the steering boxes in . We take these off and plug the centre hole on the block and drill and tap the lower hole in the filter area to 3/8 npt and grind some metal away around the face of the holes to allow -10 to 3\8npt fitting to be screwed in to the block directly taking 2 90 degree bends out of the return from the filter .
The next one is to front oil your standard block by spliting the return line from your remote filter and running it to a space between the dizzy and the oil pressure outlet and drill a hole to fit a -8 90 deg bulkhead fitting then run the line from the rear to the front right side just back from the front wall of the block above no1 main and drill and tap to 1\4 npt and fit a -8 to 1/4npt fitting so the tube runs from back to the front under the intake
My own personal preference is to not block the oil to any lifters as I have seen many roller lifters and solids be very galled when high spring loads are used there are several drop in no mod needed roller lifters on the market now .
I also run the cross over tube in all applications as I go through the top of the rocker feed gallery with 1\8 bsp thread directly above the lifter gallery's then drill a 1\8 hole in the bottom of the rocker gallery joining them to the lifter gallery's creating full time oiling to the heads when doing this mod you turn no2 and no4 cam bearings to block the oil from the cam now you have priority oiling of the crank and cam and the heads are done from the main gallery .
I also block the left lifter bank at no 1 bearing as it is oiled through the crossover tube and 1 though 4 main bearing passages are opened up to 9\32 all the way up to the right lifter bank
Just thought I would chime in for a different perspective
