Come to think of it I’d build a 350 instead of a 400 if all I could find was a 557 casting 400 block.
The beauty of owning a Pontiac is all the engines are physically the same size and weigh within pounds of each other no matter the displacement. The 455 is the best bang for the buck hands down, the 400 is an awesome performance engine as well with an edge on fuel economy.
To me it makes little sense not to maximize your cubic inches, within reason. Sometimes the 455 is a little too thirsty and the massive torque is hard to harness so the 421/428 or 400 makes sense depending on how you set up your car.
A 350 or 326 just isn’t in the cards for the majority of us, unless we’re restoring a 326 or 350 numbers matching car.

Bart, serviceable 428 and 455 blocks are increasingly rare here in the Ohio Valley. 400 blocks are still available but the prices have gotten totally stupid. There was a guy on Marketplace asking $1,500 for a 557 block.
