The 352 and 390 blocks use the same wall cores when cast. Overbore to 4.05+ won't be an issue. They are pretty much the same block. A 17/64" drill bit shank should be a snug fit between the wall cores. You access them through the freeze plugs holes.

Damn, that's something I didn't want to hear. I'm glad I got to meet him and Rosie and Rick. I'm proud to have had him as a friend, RIP Johnboy
