bushing lifter bores on 340
Yes, the hole is perpendicular to the Earth...it's at an angle relative to the bore. Similar to the Mopar instructions, it is as far towards the centerline of the engine as you can go. That's because even at that position, it places the hole a little higher in the bore than you'd like. I thought of drilling through the other wall of the lifter bore to allow drill access so I could place the hole lower but felt that would be a lot of screwing around for little gain.
Before someone catches it....the drill bit shown is larger than the .046" I actually used.
