cooling

[Larry Moeller <elmo@inreach.com>]

Lloyd Faust who races a sebring mgb re-cored to a usa core & reports it
is good...  another racer told me that the thicker core is NOT a
solution, and that he lengthened the core... I need to deal with this
cooling issue for my 62 B vintage racer, but cannot see any way to
lengthen the core due to the steering rack... i've talked to lots of B
racers & most tell me that cooling is a problem...
