Yes, I have newer SBC's mounted in my TF trucks. I don't know what year Chevrolet stopped drilling and tapping the 4 holes on the front of the block, but my 1969 350 and my 1990's 350 create motor were both drilled. Look for the (2) 3/8" bolt holes on each side of timing gear cover down low on the front of the block...
