Henry,
In my opinion an 87mm piston is the maximum that should be allowed in
vintage racing. Anything more is an obvious disregard for the spirit of
vintage racing and car preparation to period specs. However...........
if you want to go to 89mm pistons call Ken Gilanders of British Frame
and Engine in California, phone: 818/443-0939. I have heard of people
going over 90mm, but have no verification of this.
