While were looking at this side of the motor the oil pan will block off the oil return if you have an oil pan gasket lay it up there and you will see the oil return for the time tunnel is blocked off.

Yes the oil pan will cover most of the original hole that was there that's why there is more of a slot there now. I have also drilled and tapped 4 1/2NPT holes right under the cam next to the back of the mains for oil drain back. I know if gets into the swinging assembly it will cost HP but for now getting the oil back to the pan is more important than windage loss.

Are you bushing the lifters ?????will the lifter uncover the oil hole when its all the way at the bottom or all the way at the top.THIS is another big problem.... if so bushing the block is the easy fix... I would pressurize the water aND oil before I did anything..

At this point in time I am not planning on bushing the lifter bores he has moved the upper oil gallies up so it is just like a small Chevy, I told him that I wants the lifter bores under size so we could fit the lifters witch he did they were all .003" to.004" under sized. Right now the lifter clearance is .001" to .00012" I have assembled the whole motor several times and pressure tested the oil system to make sure that the oil doesn't go into the cooling jackets or in to the crankcase. I have also pressure tested the cooling jackets to 10 psi on both sides using my torque plate and the right side held 10 psi overnight and the left side was 9 psi in the morning it started at 10 psi so I don't know if the O-ring plugs leaked or head gasket or the porosity in the block. But I plan on checking the water system again after it is fully assembled. Thanks for all of the information.

You don't have to bush the lifters but I'm thinking you'll need a taller than normal lifter so that when it's at the bottom the hole is not uncovered I've had both style blocks the one with the oil hole behind the lifter and the one with oil hole in the center of the lifter. If you measure from the base of the cam to the top of the oil hole that will tell you how tall of a lifter you will need

That's good information Thanks
When I was testing the oil system it didn't seam to uncover the oil galley's with all of the lifters heads and pushrods in place but I will defiantly check that when I test it again.

Are the front of those blocks the same as the 9.0 and 9.20 R3 blocks? (bolt pattern wise).

The ones I have seen all take the low deck cover however the block could use a tall deck cover if new holes are made.

check every lifter to be sure that you are ok .they look low when they drill the galley from one side only the hole some times will wander of course. That is why other blocks are drilled from both directions and intersect one another

I just had to drill and tap (2) new holes on my R3 block for a stock 360 timing cover to work. Not a big issue

Are those coolant passages in the deck correct? Something funny looking there.


I am not causing global warming, I am just trying to hold off a impending Ice Age!

Some of the cooling passages in the deck I have added. Kent designed this block to except the P5 head so you need to drill water passages for your style of head. I used a Felpro Gasket for the pattern.

No problem, thanks for all of the input. The lifters are Morel +.300 height and .200 intake offset .904 diameter.
