It is a combination of a stock 3 3/4 stroke crank with a block bored to 3 5/16 (1/8" overbore).

With the shorter throw crankshaft, they should really rev up fast. Also, cheap to build in that you can use the earlier 59AB crank, stock 29A rods and floater bearings (which are a bit expensive and harder to setup), or just take the Ford 49-53 crankshafts that everybody has laying around (cause they put 4" merc cranks in them) and use a set of 49-53 rods with insert bearings and you're good to go. Easy engine to build with the cheapest parts available - you'll love it!

My personal favorite for a hot street engine is a 4" Merc crank and a 3 5/16 bore - 276 cubic inches.
