Bare Bones Budget 400 Build

Or even more strangely, the overlooked 400 that this thread is about!... too much "Ew. Smog motor" until people figured out it had the biggest bore of all the big-blocks at 4.342. Put a lightly machined 440 crank in it and voila... 451 in a package that looks like a 383/400 externally :)

400 usually gets a pass, if it is to be stroked, If I was to build a B engine I would drop a 3.75" crank into it even the 361 mentioned earlier would be a 406, even a .030" 383 would be a 431, but saying that nothing wrong with stock stroke.
