If you wanted I'm sure in today's market you could have a billet block made to your specs and have the bore spacing of your dreams. If all it takes is to bolt on some external parts to be considered a Pontiac engine I can come up with some adapters and make this happen much cheaper. For the most part as a group we understand the limitations of the design we are working with and can respect the time and effort it takes to make one run fast. I doubt you get that in the Chevrolet world.

If it was just the block it would be one thing. But what about heads? Sheet metal Intake manifold and header should not real be much different in cost no matter what the bore spacing. So what bore spacing should be used? One that someone else has already done for a different engine family. This will mean that there should be CNC programs to machine crankshafts and raw camshafts billets, maybe oil pans etc.
