Bare Bones Budget 400 Build

For there displacement..... super small for a “Big Block” engine, the stock parts are generous in size/performance. The after market part that fit the low deck are limiting for valve size though iit doesn’t need much.

It’s bore and stroke combo is like a small block.
4.12 X 3.38
I’d like to run that bore size in any of my small blocks.


Never understood how people disregarded the 383, if they came out with a 340 race block with spec like a 383 people would be tripping over themselves to buy one, but many have one just sitting under a bench cause it's not a 440.
