By "up" I assume you mean up to the heads/rockers. Was the block drilled for Hydraulic lifters? It was the only extra cost item when I ordered my block. I had it done so I could use push rod oiling for the top end.




No, it was not drilled for hydraulic lifters.I got a external oiling kit from Ray Barton to go from the side of the block up to the lifter galley behind the bellhousing area with -3an braided line and fittings. Tap that with 1/8" threaded T fitting and from inside go to each side of the Barton T &D rocker shaft.
Not sure if I need anything else.
