Default Question for 68 BB Owners

The 69 BB coolant system uses a pressurized expansion tank that's located on the passenger side of the engine compartment. Is the same setup used with the 68BB's?

Roy,
As per the NCRS judging guide the only big block to use an expansion tank is the L-88. It came equipped with an aluminum tank. Mine did not have one and to my knowlege no other big block came with an expansion tank in 1968.

Mt 68 L36 has the original Harrison radiator (well, at least the tanks...) and no expansion tank.
