stress relief

["Terry Hunt" <guambomb743@msn.com>]

About once a year the members of the Gold Coast Roadsters and Racing Club 
are invited to Joe Mondello's shop. Last year Joe gave a talk cyrogenics and 
shaking of race parts, particularly on blocks. I forget the exact figures, 
but stress relieved blocks maintained round bores better. Of course a 
torqued bore plate was used to simulate the torque stress of a cylinder 
head. Heady stuff. Terry Hunt, Guam Bomb, #743
