I haven't built a stroker 440 or 400 motor with a 4.250 or 4.320 stroke crank with BB Chevy rod journals and steel rods that I had to clearance the blocks a lot, maybe a tiny bit but not a lot

Not so on my current build with a KB aluminum wedge block with a 4.500s stroke crank with stock 2.375 Mopar rod journals sizes and steel H beam rods, I had to notch the sleeves at the bottom of the bores on all eight cylinders to clear the rod bolt heads
