I have spare 441 Victim engine but not about to inflict it on any chassis post 1974...actually have not figured out what it going in, B44 frame maybe.
Marc mate, would you consider swapping a fully rebuilt and nicely modified 250 Ducati NC engine for the B44 motor?
Be the envy of the Tokyo cafe racer set (tiddler class) with your own Italian Stallion!
I'm serious actually Marc, I'm considering turning my Hindall into a serious pre 70 class 4 stroker after seeing the Cavells and Lawsons B44s go at the Nats.
