questions about b20's
--------------------------------------------------------------------------------
I have a question bout these 2 cranks, I was wondering if they are the same, if not which is better, i need to know because i just bought a b20b bare block and im trying to put it back together, and piston rods are the b18a rods the same as the stock b20, NEED INFO ON THIS ASAP

you cant use the pistons cause the b18 is an 81mm bore while the b20 is a 84mm bore. sroke is the same on both which is 89mm

you can use an LS crank in a b20.....you can use the RODS of an LS in a b20, you can not use the pistons in the b20
b20=84mm
b18a/8=81mm
you could use the 81 mm pistons if you resleeved the b20 and went to a smaller bore but that would be stOOpid.
b20b/z=b18a/b cranks an rods
