Mythbuster: continuing project thread of my 1303 '75

Hi Walter,

Long time no see!
More than 400 horses, pretty impressive :O

How are you liking the AA birals so far/how are they holding up?
I was wondering why you picked the birals instead of the plain iron cylinders, I'd expect the biral ones to be a bit weaker.
And did you do any machining/honing to them or are they stock?

Cheers,
Simon
