You go 4.800 BS and there will be a 4.600 bore in it.
If you want bigger bore spacing you can buy that, and it comes with way better parts for making power as a bonus. BUT IT WILL NEVER BE A PONTIAC. JMO

If your gonna change the block and heads, intake, crank designs, you might as well just build as BBC, Ford or Mopar.
Makes no sense to start over with a lot higher cost to build an engine that no longer is a Pontiac motor division engine externally. Already did the BBC stuff for 18 years and have built a few 572 BBC's that fly, make more hp cheaper to do then an equivalent Pontiac cost wise.
Now playing with what is available and making cubes that live, make hp and torque. That's where the interest should lay.
So who has the info to stretch the existing bores with std inline heads. As to my question above.
