I run the Motown (World) block with the 350 mains with the 4.125 bore w/splayed mains. It's now bored to 4.155 with at least one more bore left in it.................Never had a problem with it. Also love the blind tapped head bolt holes it's easier to run head studs. I would take a look at the motor that's for sale in the parts section, you won't build it for 4500.
