Are you a machinest? I'm not If you can't eyeball the edge distance of the existing hole and tell if it's a candidate for increasing the bore... All my blocks are drilled with a hand-held drill and the correct tap, even the mundane daily driver blocks. I drill 'em all the way to the intersection and then use a rotary burr to smooth out the sharp corner. (easier with the larger hole) I figure I gotta get a new pickup anyway and the 1/2" price isn't that bad when included in a complete overhaul.

I do it the same way, except I first use a die grinder to remove the threads 180* opposite the thin side. This moves the drill center point over, leaving more material at the thin area and reducing the chance of cracking. Another advantage with 1/2", it takes less power to turn the pump.

I made a new one up for the 340 from the 3.0 Mitsubishi engine (a full 1" ) attached off the cover into the rear sump Magnum pan. Has that nice bell on the bottom too. Mike would you have a pic (or a part # to search for a pic)? EDIT found one on eBay, that would be a nice piece & an easy mod especially if you have a rear sump pan.

I had to section, shorten, then tig it back to get it in the right direction, like making a header. If you still need a pic i'll send you a pm to show how it came out.

When I've tried moving the hole outboard the pickup pipe hits the pan side wall....have to dimple it. Might depend on who makes the pan.
