.040" over 400 would be a 408...unless it's also been stroked.

how do you figure that.

 

[tRustyK5]

A very common example is a .030 overbore 400 is 406 cid. Your's is .040" overbore so 408 is pretty likely. The only way to gain much more is to run the 3.85" stroke crank. Stock stroke for a 400 is 3.75".

Unless someone has found yet another way to squeeze a few more cubes out of a small block, 434 cid is as big as it gets. That would be the 3.85" crank and an .060" overbore.

Generally boring a motor out doesn't gain you more than 5-8 cubes.

world industries has 454 small block. Thats with there block though, so its prolly a lil differant

Maybe a taller deck? There is only so much physical room to work with, unless you get into the cooling passages, sleeve it and only run it 6 or 7 seconds at a time.

one of the big dawgs here runs a 454 cubic inch small block, i forget the stroke and bore, but its based off of a motown block and he has brodex heads on it, its blown and makes over 1100 horspower... pretty kewl if you ask me..

BTW, bill mitchell makes a 454 cubic inch small block also.. only 650 horsepower or so but its naturally aspirated.. Nate
