According to this, the as recieved weight is 167 lbs.
24502650— Bow Tie CNC Racing Block “Short Deck”This “CNC machined” cast iron bow tie block has an 8.200" deck tocrankshaft, compared to the standard block with a 9.025" deck. This block isdesigned for small cubic inch engines used in drag racing, road racing, orrestricted oval track racing. The factory bore on this siamesed block is 3.894"“and can be bored to a maximum of 4.190"” with a minimum wall thicknessof .250". The camshaft has been raised up 4.953" and the main oil galleryrelocated from above the camshaft to the side of the cam. The water pumpholes are spread and a big block water pump must be used. When a 6" orlarger damper is used, the pump must be raised with aluminum adapters.With the shorter deck, the pushrods must be shorter and mate with the camand lifters. The main bearing diameters are 2.30", not the standard 2.45". Thecam bearing holes are bored for roller bearings at 2.250" diameter O.D. x1.875" I.D. This block features five steel main caps with the three center capssplayed at 20°, and the block weight is approximately 167 lbs.
