Vintage Spitfire Race Car

[JLorenz@PerfectionCorp.com]

I have just purchased a "barn find" '65 Triumph Spitfire vintage race car.
It has been stored in the barn for about ten years. Current owner is not
sure of the engine displacement and I don't know too much about Triumphs.
Can anyone tell me what size engine came stock in these cars and what the
bore/stroke would be? Also what horsepower?

Thanks,

Jim Lorenz
