The B type (low deck big block) 400ci engine is a 383 engine with a slightly larger bore. 4.34" x 3.38" Bore and Stroke. This engine is slightly rare, but a good find. Using a 440 crankshaft in the 400ci engine makes a stump pulling engine larger than a 440! Even stock the 400 has serious potential with its short stroke to make a dependable engine.
